High frequency power measurements

Hey,
I'd like to know if there are developments in measuring electrical high frequency signals with labview without using an extern power analyser. At the moment i'm using a yokogawa power analyser but i'd like to know if it's possible to log HF signals without the help of a power analyser... Are there NI products on the market for this purpose?
Thx,
Andy

Hello,
In the case of frequencies up to 200 KHz, NI can provide several solutions using the 'standard' data-acquisition boards or digitizers (scopes), from a low to very high accuracy solutions.
A good solution can be one of the high speed M-series boards (PCI-625x).  These boards have up to 32 multiplexed channels with a resolutions of 16-bit at a speed of 1 MS/s  (500 KHz).
A better solution would be a S-series boards.  These data-acquisition boards sample all input channels simultaneously.  We have boards with 2, 4 and 8 channels and sample frequencies of 10 MS/s  (up to 5 MHz if needed).  S-series board are the boards with product numbers PCI-61xx.
The best solution is to use a digitizer (scope).  Also here a lot of possibilities going from low to higher bandwidth and resolution.
The most flexible is the PXI-5922.  A 24-bit digitizer if you sample @ maximum 500 KS/s.  This board only exist in the PXI platform.
Then NI has 8-bit digitizers (normal resolution for scopes) from 15 till 125 MHz bandwidth.  If you need a higher resolution they have solution up to 14-bit (very high for scopes) @ 100 MHz.
Please give your local NI Office a phone call.
They have technical engineers who can discuss your needs and provide you a solution.

  • RMBP - high frequency/power noise when doing file operations?

    Hi,
    I noticed today that my new rMBP is emitting some strange high pitched noise, especially when doing heavy files operations like spotlight indexing or startup of the computer. It's louder and more prominent when I connect the AC adapter. It sounds like some power interference, a bit like some broken chargers do or Iphone 4s when transmitting 3G data.
    It's not very loud but I can hear it clearly, when sitting in a silent room, even without closing my ear to the Macbook.
    Has anybody noticed that or can advise something? Is that normal with those machines or some issue that has to be fixed? I really don't want to return it, as it is perfect otherwise...
    Thanks in advance for feedback.

    here is the link to a sample of that noise. Please listen from 15 second:

  • High frequency measurement 2 counters range

    Hello,
    I know this info is somewhere but I can't find it.
    When using a Counter/timer to measure frequency there are multiple methods.
    i.e. Low Frequency with 1 counter and high frequency with 2 counters.
    What is the definition of a "low frequency" and what is the definition of a "high frequency"?  i.e. low frequency = frequencies below 100 Hz 
    Also what is the definition of a "large range"?
    Thanks
    Dan

    Hi Dan
    There isn't a specific bandwidth that is defined for use with either the one-counter or two-counter method. However, located in the NI-DAQmx help file there is a section detailing the quantization errors that arise when using either method with a variety of input frequencies. By referring to this information you should be able to determine which method will produce the smallest error in your application and hence which method will be preferable. This help file also explains the errors associated with the large-range two-counter method.
    To locate the help file, you should select Start»All Programs»National Instruments»NI-DAQ»NI-DAQmx Help, and search for 'quantization error'.
    I hope this helps, just let me know if you'd like anything clarified or if you have any other questions on the matter.

  • DAQmx Error 89137 When trying to make a high frequency measurement.

    I am using a PCI-6602 Timer/Counter for multiple measurements on a serial interface...
    I have the clock line connected to Gate0, the enable line to Aux0 because I need to make a two-Edge seperation measurement between the two later...
    But I also want to make a "Period/Frequency Measurement (High Frequency with Two Counters)" measurement...
    This requires that the signal to be measured is on Source0...
    I implimented the following Code:
    void meas_FP_Freq(float64 *Freq0, float64 *Freq1)
    TaskHandle CLK0_Freq, CLK1_Freq;
    DAQmxCreateTask ("FP_CLK0_Freq", &CLK0_Freq);
    DAQmxCreateTask ("FP_CLK1_Freq", &CLK1_Freq);
    DAQmxConnectTerms ("/Dev3/PFI38", "/Dev3/Ctr0Source", DAQmx_Val_DoNotInvertPolarity); // Gate0 to Source0, No Error....
    DAQmxConnectTerms ("/Dev3/80MHzTimebase", "/Dev3/Ctr1Source", DAQmx_Val_DoNotInvertPolarity);
    DAQmxCreateCIFreqChan (CLK0_Freq, "Dev3/ctr0", "", 6000000, 6500000, DAQmx_Val_Hz, DAQmx_Val_Rising, DAQmx_Val_HighFreq2Ctr, 0.001, 4, "");  // High freq measurement

    DAQmxReadCounterScalarF64 (CLK0_Freq, 3.0, Freq0, 0); // Run-Time Error -89137 Specified Route cannot be satisfied..etc
    DAQmxReadCounterScalarF64 (CLK1_Freq, 3.0, Freq1, 0);
    DAQmxDisconnectTerms ("/Dev3/80MHzTimebase", "/Dev3/Ctr0Source");
    DAQmxDisconnectTerms ("/Dev3/80MHzTimebase", "/Dev3/Ctr1Source");
    DAQmxClearTask (CLK0_Freq);
    DAQmxClearTask (CLK1_Freq);
    The "Low Frequency" method works fine, but the resolution is too low...
    Every help file I've read indicates I can use different PFI inputs for measurements... What am I missing?

    Hi,
    The reason that you are getting the error is the PFI lines are being reserved twice. You don't need the DAQmx Connect Terms functions in your code because the DAQmx driver does this for you automatically. If you still receive an error after doing this, try to changing the low frequency counter number.  I hope this helps you with your application.

  • Sound Power Measurement with 4472

    Is onboard DSP a must for any Sound Power Measurement?
    I know that NI-Sound Power Plus works only with 455x.
    Is it simply because NI has not yet written a software for Sound Power Measurement using 4472 or is it technically NOT possibly to do Sound Power Measurment using 4472?

    1. The 6036E is a "sweet" card for high-speed, high-accuracy DAQ on the PCMCIA bus. Even at 10-times oversampling you can achieve 15-20 kHz of response with nice line resolution in the FFT. My experience with the PCMCIA bus has shown a wild variation in DAQ bandwidth (IBM/Compaq...the PITS -- Dell...the best ; and , no I do not work for Dell). For signal conditioning, I use SCXI (so I can not comment on the use of the other components). If you can live with interchannel skew, the set up looks quite promising. Our DAQ requirements demand the use of simultaneous sample-and-hold (SCXI 1140) for either two-channel hot-film measurements or multiple sound pressure measurements with precise cross-correlation (to eliminate wave reflections and e
    chos within the test article). Our microphones were developed by NASA for use in VERY HIGH temperature environments, so our signal conditioning ahead of the 1140 is made from custom devices.
    2. It is important to note that any toolkit add-on to LabVIEW "could" be written by the end user using the very same subVIs distributed with the Full Development System. Sound power is merely a term used to describe a particular mathematical method involved in transforming the acquired sound data from the real domain to the frequency domain. The mathematical methods have been used for many decades. I use my own custom code originally developed in FORTRAN, converted to C++, and now embedded in a code interface node (CIN). The issue to resolve comes down to a) do you have the in-house capability to write and support detailed code development, or, b) do you purchase the toolkits and thereby achieve the capability very quickly. Although the toolkits are expensive, the burdened cost of, say, 1
    additional highly-skilled employee could cost 20 times as much.

  • Regza 40" LCD TV emits high frequency noise

    A few months ago I was lucky to win this television, a 106 cm Regza HD LCD.
    I was very pleased because I could never have afforded it myself, and I am very happy with its performance generally.
    What I find however is that it emits a high frequency noise that triggers tinitus to my hearing. (Tinitus is a high pitched squealing noise heard by people who have damaged their ears, sometimes called ringing in the ears).
    I guess my hearing is already sensitive through listening to lots of live music over the years, but I think that this noise is excessive.
    I figure that a monitor this size is using a fair amount of power and that maybe the power supply could be overworking itself.
    The monitor emits this noise at a consistent level even before the sound from the tv show begins.
    I am interested to find out what suggestion forum users may have for reducing this background noise?
    The monitor is still under warranty as it is only 6 months old.
    I wanted to be prepared to discuss it with Toshiba warranty people if forum users can suggest first of all what could be causing the noise, and secondly, possible ways of addressing the issue.
    Thanks petekey4

    Hello Pete
    As you can see this is Toshiba computer forum and I don't believe you will find many people here who want to discuss about Toshiba LCD TV.
    Anyway, if the TV is new and with valid warranty the best option for you is to contact service people and let them check your new TV.

  • High frequency quadrature decoder (NI PCI 6221)

    Hello, i would like to ask you about high frequency quadrature decoder. I am using module in DAQmx for measuring linear position. For this i am using NI PCI 6221. My problem is that i want to use this for my interferometer and we need really high speed. So I tried to use External timing whitch should be possible for this card up to 80MHz. Unfortunatelly i always will get error message that there is some kind of owerflow and my program crashes. So my question is how to get all data form this card. I know that the buffer size FIFO is only 2 so if it is impossible to get all data so i want find another solution. Is it possible let my card work alone on 80MHz and only repeatly rewrite all buffer and just sometime ask this card for sending current buffer. I dont really need all the data, but when i will ask i need to know reall position. This high speed is really necessary because my interferometer is sensitive and i dont wat to lose any steps. If there would be any possibility how to work on 80MHz and only sometime ask for sending data with position, it would be great. Sometimes i will ask not for only current position but for full buffer because i want so see what is happening during some time period, but this task will be only sometime. 

    Dear BMAJTZ,
      The counter frequency (the maximum speed available) is configured by the Task in the background. In our case, the counter is set to detect edges, so it always uses the maximum speed available. If an edge occurs, the count value increases by 1, and this accumulated count value (stored as a binary number) is read by the DAQmx Read VI, and converted to meters. So if your encoder input is slow enough for the 80 MHz card to handle, you won't miss any ticks, even if you only read the value occasionally.
    You can find further information about counters and encoders on these links:
    http://www.ni.com/academic/students/learnlabview/digital.htm
    http://www.ni.com/white-paper/7109/en
     Also if you can tell me the approximate frequency of your encoder signal, and how often you nedd the position info, I can do some benchmarking for you to see if your card is capable of the task.

  • Bandpass filter amplifies only noise at high frequencies and saturates the opamp output

    I have designed a fourth order bandpass filter using the opamps TL081C. It is designed to operate at a center frequency of 40 kHz with a bandwidth of 2 kHz and a gain of -12.5 . I am using an SCB-68 board for data transmission and reception, one channel each for transmitter and receiver. I have grounded the adjacent channels to both the transmitter and the receiver in order to avoid crosstalk. However, at the output, I get a signal which looks like an amplitude modulated signal and is, most probably, noise. The amplitude of this signal is always around 9V, no matter what is the amplitude of the input (even if the input is 0V, the result is the same). If I scale down the whole BPF to operate at a center frequency of around 20 kHz, everything works fine. Therefore, I think the problem lies not in the design of the BPF but the use of the board at higher frequencies. Please reply as soon as possible.

    You have done something wrong. You should read the manual for both the SCB-68 and your DAQ card once more. In such cases I often use MAX, and a battery as source. Then a DAQ input is not connected (floating) you will see measurements like you are doing now. Some high level voltage often modulated with mains frequency.
    Besides which, my opinion is that Express VIs Carthage must be destroyed deleted

  • NI Mydaq gain loss at Higher frequencies

    Hi There,
                      I am using a MYdaq for my student project, I am using this is an audio sine wave generator and analysis tool as part of the project.
    I am sampling well above nyquist of my highest frequency (20K) at 100K sample rate both on my OP DAC and IP ADC and I have a buffer size of the same size on the I/P and output.
    I am using the audio L/R inputs and outputs (AC coupled) - This is looped fro the purpose of this excercise.
    When I generate frequencies (via the Sinewave Vi in labview - "NI_MABase.lvlib: sine waveform.vi"  and my FS and #s is both set to 10000.) i get a drop in level above approx 10K starting at about -1dB up to -3dB at 20K
    Can anyone help me in tracking down the cause of this?
    Regards

    Hi,
    Just to for my own sanity, have I got these values right? 
    - Sampling at a frequency of 100kHz. (Analogue Input and Output)
    - Intending of sampling a 20kHz signal.
    The specifications of the NI myDAQ can be found here. These specify that the device can sample up to 200kS/s for both Analogue Input and Analogue Output, meaning that the maximum clean sinusoid we can both generate and acquire should be 20kHz, with 10S to represent the wave. Higher frequencies will require lower samples and the signals will look more chopped and aliasing will occur (20kHz*10S = 200kS/s). In order to appropriately measure the 20kHz wave, we need to choose a maximum sample frequency of 200kHz for clean waves. With this in mind 100kHz sample rate should be okay.
    Is it possible for me to check the code that you have written so far? What I imagine could be happening is that we're seeing these issues due to the slowness of software. If you look at your code and the DAQ VIs are continuously having to check what values to write, rather than having these values delegated down to the hardware layer prior to running the task, this could be the source of the issue. This is because in software, there is a maximum update rate of 1kHz; this is why all of the base clocks in LabVIEW software are 1kHz clocks. If we're constantly having to poll what kind of digital output values we want to write, this will affect the consistency of the generated signals.

  • NI PCI-6115, problems in high frequencies

    Hi,
    I'm not sure if this is the right place to make this question but let's try..
    I try to measure the frequency response of the output impedance from a certain switched-mode converter using NI PCI-6115 (I inject sinusoids into output voltage and measure the output current). I get a nice plot but there are some problems in high frequencies. It seems that the measurement card makes some unexpected peaks. I use the network analyzer (Venable) to verify the results and beyond 200 kHz the results do not match. I attached the plot with the results from both methods (MC = PCI-6115, Venable = network analyzer). Does anyone have any idea what could cause this difference in high frequencies? The measurement set ups where exactly identical. 
    Thanks!

    looks like a resonace at 400kHz...
    Are you shure that the input impedances of both setup are the same? Are you injecting with a transformer and build a LC resonator with the MC?

  • High Frequency Noise from Headphones Out Jack

    I have isolated the following issue to audio that is monitored via the headphones output on the back of my iMac:
    I've been encountering a very high-pitched (and at times a cycling through high frequencies) noise when working with headphones to monitor audio. It's not the headphones and the problem is not limited to any single application. The noise is sometimes barely audible, and it comes and goes - but repeatedly and often. Sometimes the frequency of the noise is so high that I can imagine that those with poor or compromised hearing wouldn't even notice it. But the highest frequencies are still detectable - kind of like a faint ringing in the ears or a ringing television set that has its volume turned all the way down.
    I've done everything I can imagine to troubleshoot the problem including asking a Mac genius, but nobody seems to have encountered this before. The noise can be triggered off (not masked) by any other incoming audio, but eventually it reappears. I will be editing a file, the noise will appear, and I can literally silence it for the moment by pressing a volume key or playing back a portion of audio.
    Anyone else experiencing this issue? Is there a fix? I do a lot of audio engineering and this problem is very distracting. I haven't purchased any outboard gear to monitor with yet, so I don't know if I will hear this noise through an external audio interface or not. Thankfully, this noise isn't being recorded to disk. It appears to be a little monster that is haunting only the playback.

    OK, It is very easy to reproduce the problem, just follow this steps:
    (1) Insert any headphones to iMac.
    (2) Do NOT play any iTunes or any application with sound.
    (3) Now, set volume with the volume control keys on your keyboard, set it to the MAX.
    (4) You can keep pressing on the increase volume key and every time you hit the key you should hear a sound.
    Just as when the sound stop, you will hear a high pitch. Keep repeat step 4 and wait a while, then occasionally you will hear a high pitch sound that will last to longer than 30 seconds. The high pitch will be even easier to reproduce if you alternate before decreasing volume and increase volume by 1 level, each time, wait and you will hear the high pitch too.
    This high pitch sound can be heard on external speaker plug into the headphone jacks too.
    BTW, I turned OFF WIFI, Bluetooth, removed all USB devices except keyboard and mouse, adjust monitor brightness, they have no effect on the high pitch, it is still there!
    I am going to call the Apple Care tomorrow. Will keep you guys posted.

  • Facility High Rx Power on 10DME card

    Hi all
    I found message "Facility high Rx Power" on 10DME card. So, I need to know what is the root cause and reason to get the message. Please give me the idea or comment.
    Thanks
    V
    Note: Please see the picture from attach file

    it is -8dBm threshold set on 10DME.
    it is by default.
    http://www.cisco.com/en/US/prod/collateral/optical/ps5724/ps2006/ps5320/product_data_sheet0900aecd803fc51a.html
    in the link given above search for "DWDM Receive Side Optical Performances"
    so by default we have a threshold of -8dBm high-Rx power and -20dBm for low-Rx power.
    so now question is that from where we start getting -7dBm on trunk port, this we can ignore for now, as -7dBm is fine will not cause any issues.
    so to clear alarm you can either change threhsold and put a 3 or 4 dB attenuator pad on trunk port of this 10DME.
    i don't know your design, but we can even change VOA on add-drop cards.
    but as i said -7dBm is fine, so just change threshold for now.
    let me know what we need to do.

  • Power Measurement Take Too Long

    Hi All,
    I am using Agilent 8163B
    with 2 slots:  81619A (2 heads) and 81618A (1 head) for power
    measurements.  I setup my measurement with Agilent's time sutup driver
    vi at 5 seconds average time.  However it took over 20 seconds total to
    complete the measurement of 3 channels using the Agilent's 816x Read
    PMW Value.vi (this VI calls a DLL hp816x_32).
    My
    question is that can I get this measurement done close to 5s with a
    parallel read of 3 channels at the same time?  i.e., Is the DLL
    hp816x_32 reentrant?
    I tried to have a parallel wiring of
    816x Read PMW Value.vi to test this, but still get a measuement time of
    21 second.  Does anyone has a suggestion to improve this?
    Thanks,
    Bryan
    Solved!
    Go to Solution.

    Lynn and Bill, thanks a lot for following up on my questions.  In my testing VI module I put "fetch" vi in a while loop after sending "initialize" and "average time" commands outside the loop.  When I set the "averaging time" to 5 seconds, I can see the power values from 3 channels are updated at about every 5 seconds. At the same time I monitored the loop index which updates at a far faster rate. This behavior must suggesting that the "fetch" vi was getting the same value within that 5 seconds when my loop was running repeatedly.  This value must be an average value as it didnt change within the 5second time window.  I guess my observation is indeed different from what Lynn posted. I did come across the programming guide yesterday as shown in Bill's link, but didnt look in detail, you know how we LabVIEW programmers got spoiled by the graphic code
    After another look at the guide, it made more sense to my observations, i.e., Fetch command returns an average value right away and you can fetch all 3 channels. While the Read command triggers an measurement and exclude access to other channels after one read command was sent.  I also googled arount a little, and found the following text (not exactly for 8163B though) maybe also helpful to others in a similar situation.
    Thanks again
    Bryan
    The READ? command provides a sequential method to make
    measurements and retrieve the results. READ? will hang the GPIB bus
    until the measurement is completed, or until the timeout value has been
    exceeded. Associated SETup commands (for each measurement) are used
    with the READ? command to retrieve desired measurement results in a
    sequential manner.
    Sending a READ? command is equivalent to an INITiate/FETCh cycle for a
    measurement. A READ? command executes an abort action on that
    measurement followed by an INITiate and a FETCH?.
    READ? commands can be mixed with FETCH? queries in order to make
    combinations of sequential and overlapped operations. One measurement
    can be issued a READ? command (sequential), and the next measurement
    can be issued INITiate/FETCh? commands (overlapped), if necessary.
    The advantage of using the READ? commands to obtain measurement results, as opposed to the INITiate/FETCh method is:
    It is simpler. Fewer commands are required to obtain measurement results.
    Some disadvantages of using READ? over INITiate and FETCh are:
    The test set does not process any additional GPIB commands until the requested measurement results are available.
    The sequential nature of the READ? command does not allow the user to
    make concurrent measurements. Concurrent measurements require the
    overlapped commands INITiate, DONE? and FETCh? .
    The READ? command does not provide measurement results such as statistics that are available using the INITiate/FETCh method.
    The READ? commands have pre-defined measurement results. If additional
    results are needed from a measurement they may be obtained with a
    FETCh? query.

  • VI for capturing data at high frequency

    Hi,
    I have been trying to build a VI, which would read data from a machine at around 50KHz. I am accepting one analog signal from this machine, converting into digitized values and storing ALL the digitized values into a file. I could not afford to loose even one data. I would really appreciate if anyone has an example as to record data at such a high frequency.
    Thanks in advance
    Dhawal

    One channel running at 50kHz is simple - in fact in the world of DAQ it's not even very fast. Check out the examples for seamless data acquisition. Basically, the idea is to set up a circular buffer that the DAQ writes to and LV reads from. As long as LV extracts the data faster than the DAQ is inserting it the process can run forever.
