Noise on my input signal at each reading half buffer

I use the PCI 6033E board.
Normaly, my signal is around 0 Volt, but at each reading half buffer, I receive a noise, and my signal come back to zero.
I find this problem on Channel 2.
Thank's in advance for your help.
Best regards

Hi,
Have you the same problem with other channel, or only with channel 2 ?
If you make a test in Measurement & automation explorer (Test panel) in continuous mode, have you the same problem ?
Perhaps channel 2 in your board is broken.
You can test your board with DAQ diagnostic utility : http://digital.ni.com/softlib.nsf/websearch/FEA4D55E1B3DA33A86257076006AA260?opendocument&node=13206...
And after, you can call National Instrument to repair this, if your board has a problem.

Display FFT of input signal which receive from VISA read ?

Hi.
I receive data from MCU whcih sampling frequency is constant and we assumed it is S. now I get data from MCU with using VISA read block. I can display data, perform some functios like filtering, multiply and save them in txt files. all thing is OK.
but when I want to see FFT of incomig data on chart , it doesn't work !! I use this VI for calculate and display FFT of input signal (from VISA read) and display it which in Y-Axis is magnitude and X-Axis is frequency.
in your mind why this is not work and what I must done for show input signal FFT and frequency components ?
Thanks.

If I understood this correctly, you are getting the correct results when outputting to a text file but you are not able to see the results when trying to output to a chart?
This discussion may be of some help to you.

High current causing noise on thermocouple input spoiling reading.

I have a J-type thermocouple I'm measuring using a PCI-6036E and an SCB-68. The thermocouple is attached directly to a charging/discharging capacitor - once the rms current through this cap reaches above about 80A noise on the thermocouple input causes the temperature reading I'm getting through LabVIEW to sink to below -10000 (which is obviously incorrect). Below about 80A rms it works fine and when I connect the thermocouple to a meter instead of the SCB-68 it works fine. Is there any kind of input buffer I should be using inside the SCB-68 or some kind of software compensation I can perform on the reading?
Thanks!
Neil

Neil-
I'm pretty sure that your inputs aren't isolated. I'm convinced that that is the problem. I've seen this problem with Fieldpoint hardware, and was unable to use it for my project. We are reading thermocouples near 230 amp heaters. I had to use a Yokogawa Darwin unit that has 500V common-mode voltage isolation, which is different than regular isolation. Most analog input devices have a common-mode voltage limit of about 5 volts. Even though your thermocouple may be putting out millivolts, that differential is riding on top of some other voltage that is being induced by your equipment. An averaging filter may make your data look better, but it won't be correct.
If you are only looking at one t/c, you may want to get a signal cond
itioner that converts the temperature reading to a higher level analog.

Generating an input signal

I have completed the FPGA Module tutorial and I am attempting to generate an input signal, but i really don't understand exactly what is going on in the tutorial. I have two FPGA I/O nodes in the FPGA VI that are labeled "ADC 0 PORT A_I" and a corresponding one labeled Q as well. I'm assuming that these generate a sine wave that the tutorial used as the input signal. I want the input to be a sine wave with noise, and Mauricio suggested using DDS, but I don't know exactly how to add this to the existing FPGA VI that I created in the tutorial. Can anyone help me out on this one?

I'm a bit confused by your post. The FPGA Module tutorial guides you through the creation of a VI that acquires a signal. The I/O nodes labled "ADC 0 Port A I" and "ADC 0 Port A Q" are the I and Q elements of the acquired and downconverted signal. Just to be able to test this code, the HOST VI also configures one of the Analog Output channles in "Single Tone Mode" and therfore generates a sine through it. However, the FPGA is not doing anything to generate the sine tone, it's the DAC which is configured to generate the sine tone.
The I/O nodes that you need to use to generate signals are the "DAC 0 Data" and "DAC 0 TxEnabled". You will also need to use another clock, the "DAC 0 IQ Clk".You might want to read some documentation on the Analog Output and look at the IQ Output example. You can find the documentation on this post: http://forums.ni.com/ni/board/message?board.id=ifrio&message.id=140

No Input Signal to Monitor

Previously I had may Mac Mini being displayed through my HD Television. I have since moved it into an office. Before moving, I used the Mini DVI adapter and the cable was DVI to HDMI into the television. Now, I am trying to hook it up using the display port adapter to DVI, with an adapter on the DVI part that allows me to use a VGA cable to hook the monitor up. Each time I try and hook it up, the monitor keeps giving me a "No Input Signal" message. Am I losing the signal when I attach the adapter that allows me to use the VGA cable? Never attached an adapter to an adapter, but I know the monitor works because I hooked it to another computer and it works just fine. The VGA cable works just fine too. Any help is greatly appreciated.

Yes, it came with one, but got a display port adapter because both our laptops have the display ports rather than the Mini-DVI ports. Wanted to try and get something that was more usable for each Apple product we have, that way I avoid having to buy more "stuff" specific to each computer. I guess I will have to try and just get a DVI/VGA cable to avoid the adapter issues. Thanks!

Would like to know the meaning of the Input Signal Channel Indicators on Denon 2311CI

The manual has no information on the meaning of these indicators on the display. For example, why is it that when I have a DVD or Apple TV as the source, the Input Signal Channel Indicators on the left side of the display show only LF and RF (left front/right front), while it shows LF, RF, C, SL and SR (left/right front, center, left/right surround) when I have my satellite box tuned to the major networks?

When you connect a device that has only stero output (not multicahnnel sound), then you will only see the standard stereo menu, Your apple products do not output multichannel sound, at least not in the manner you have them hooked yup to the reciever.

No input signal after creating a new track in logic 9

i am working on a song and have 14 audio track used and 5 midi . i try to create a new audio track but i have no input signal ,only the output is working.i did a upgrade recently but i am not sure if that is the problem.can someone help?
ps: i have no input if i record or if i playback,but it does record and i can adjust the volume ,just no signal

have you selected the proper input on the channel strip that matches the one your instrument or mic is plugged in to?

Monitor "no input signal"

When I turn on the computer and the monitor, the monitor does not recognize a signal from the computer. I have tried restarting the monitor and the computer, unplugging all cables including the power cables and reconnecting, I re-seated the graphics card, I tried using the VGA cable, but the monitor still seemed to be trying to recognize a DVI connection, even though the VGA cable was plugged in. Right after I turn on the monitor it says:
VGA input, no input signal
> DVI input, no input signal
recommended setting, 1680x1050
After about 2 seconds it goes to sleep and that is it. No mouse clicks or keyboard strikes bring the monitor back. I know of no way to change any settings, reinstall drivers, etc. , because I cannot get the monitor to work, so I am effectively blind, whenever I want to test something out I have to manually shut down the computer and turn it on again. I encountered this problem in the past, and after much frustration and unplugging/re-connecting, the problem seemed to magically solve itself, but now it is back and nothing seems to work. The frustrating part is that it seems random, this started happening a few days ago when I tried turning on my computer.
the computer is a HP Pavillion d4996t, the monitor is HP w2207
Message Edited by Tech-no on 01-20-2009 05:05 PM

Going to the control panel and turning off the monitor's power saving mode utility fixed this problem for me. Only four years of putting up with "no input" on an ugly black and white screen before I figured that out!

I would like to tare (rezero) the input signal from a forceplate (glorified

I would like to tare (rezero) the input signal from a forceplate (glorified scale) so that the base signal is set to zero, e.g.: a button on the front panel that resets the signal to zero prior to getting a measurement from a subject.
We calibrate the force plate through labview and input our new equation into our scaling and mapping box which sets the signal to zero (or near zero) and the change in newtons (force reading) is accurate but when the application is closed and reopened the signal does not always start at zero (-400 to +1200 N), while the change in newtons is still accurate. I am NO engineer, I have Forest Gumped my way into getting some nice working VIs but I can't seem to find this function.
Thank you very much for your time.

Maybe that is the limitation of Acquire Input Data.vi.The vi can't identify the Unformal key.
You can try to use Event structure and set to listen "key down" event.
There are two terminals VKey, ScanCode will sent out the information when you press key.
There are two pictures in attached file, 2.jpg will show you the detail.
Good luck.

How to create 2 output signal locked in phase from a one input signal

Hi all,
I have a case in which I want read in a signal analog input (voltage) from a photodiode, I want to create a 2 sinewave signal locked in with same phase as the input signal and output them as analog output to my 2 laser diode. the frequency of the input signal is low aroud 15 Hz , the 2 output signal i want to be around 120 hz and 150 hz .
I am using USB - 6003 daq card.
I have created a vi to see the input signal but I dnt know how to create 2 signal from the waveform generator locked in the phase as the input signal. I have seen a PLL vi , but dont know how to use that with my program.
can any one tell me how to proceed.
thanks

Hi AnkitG,
Here are a couple of links that might help you understand a little more how the PLL work and a way to synchronize the task to perform a PLL.

Also, you should be able to find a lot of examples on how to accomplish the synchronization of tasks on the community, if you consider that the only consideration is that both must start at the same moment.
I hope, these examples might show you some useful concepts:

Allow a different input source for each document

I just received my new MBP and am really happy about it. I'm a switcher so apologies in advance if this question is silly...
I use both Swedish and English keyboard maps. I can switch between them using a shortcut which is fine. However, in the International settings I thought "Allow a different input source for each document" would mean that the input source I use for a specific application will be used as long as the application is running and I don't change it, no matter what source I use in other applications.
For example: I have the English input source as default. Then I open text edit and change the source to Swedish and start typing. So far so good. I then change to another application...
Ok, it seemed that I might be able to answer this myself... as I test I noticed the following:
If I start typing using a source in an application THEN the source is retained. If I just switch to an application, change its source the source is NOT retained and will take the previous one.
Now this is all and well as long as the application you are using actually presents you with a text area to write in. But there are many applications where this is not the case (where you open windows to type text). A really good example is an IM client. Lets say Skype for example (yes I know.. iChat). Until I actually start a chat there is no text input window (well there is one..) which means that it will pick up whatever source was used previously. If I keep all the chat windows open thats fine but as soon as I reopen a windows I might be forced to change the source again
I hope I haven't overcomplicated my question which is simply what to expect when "Allow a different input source for each document" is used (I know it doesn't say "application" there and that might actually be a hint
Many Thanks for any comments

It's not a silly question, but I don't think there is an answer either, as it's not clear exactly what that setting is supposed to do, or if it actually does something consistently for various different kinds of apps.
If you have not already done so, check the box for "show input menu in Finder" in system prefs/international/input menu, so you can see which layout is active at the top right of the Finder.

Input signals out of range change settings to 1440x900 - 60Hz

I bought a new HP ENVY, I am now trying to re set up my former HP pavilion ..but I keep getting this message on my monitor"Input Signals out if range. Change settings to 1440x900 - 60Hz". I can not get past this! Help!

What is the exact model of PC you have?
What model is the monitor?
It sounds like the PC is trying to transmit the video at a resolution greater than what the monitor can support.

Acquiring two input signals simultaneously

Hi,
I have an LVDT and a force sensor (both attached to a motor) plugged into my SC board and I am trying to read out & save the output data from both sensors simultaneously while the motor is in motion. The SC-2350 board is connected to the laptop via DAQCard 6036E . Two questions:
1) in my block diagram, the DAQ assistant blocks for both sensors are wired to their respective waveform graphs (one for the LVDT signal and one for the force signal), the whole being included in a while loop (which remains true until the motor stops moving). When running the program, only one signal is read out at a time and I have no control on which signal is transmitted (this seems to occur in a random fashion). Do I need to "link"/synchronize the two DAQ assistants in some ways so that both signals will appear simultaneously? If so, how would it be possible?
2) ideally, I'd like to read out both input signals on the same graph (with 2 different y-scales but the same time scale) to observe the phase shift. I tried to "bundle" the two data output coming from the two DAQ assistants but it resulted in an error saying that the two outputs were of different types. Is there a way to plot these two physical quantities on the same graph even though they're different and come from different sensors?
Thanks for your help!
Thibault.

Hello Dani,
I assume, based on your position sensors and the image you posted, that you are using counters to acquire your data. Is this correct? If so, it is important to note that you cannot add multiple counter operations to a single task because they have different timing requirements and all channels in a single task must share the same timing and triggering. In fact, if you attempt to add a second counter channel to a DAQ Assistant for a counter operation, you will receive the following error when you try to close the configuration window:
So, you will have to use two different tasks to acquire your counter data. You can do this either by using two separate DAQ Assistants or by using two different tasks in the NI-DAQmx sub-VIs in LabVIEW. Since you are trying to compare the phase difference between the two measurements, you will also need to synchronize the operations so that you are reading from both counters simultaneously. There are several resources online which discuss synchronizing counters, and I have linked some that I thought might be useful below:
KnowledgeBase 1JPES6LL: How Do I Synchronize a Buffered Quadrature Encoder Measurement to a Signal
KnowledgeBase 3GGATSCC: Hardware Counter Start Trigger for Counter Synchronization
It would probably be easier to use the NI-DAQmx Sub-VIs to implement this synchronization because they give you more control over specific parameters of your task. You can use the NI Example Finder to browse some examples which use the NI-DAQmx sub-VIs for counters. You can open the NI Example Finder by going to Help>>Find Examples... in LabVIEW. Once in the NI Example Finder, you can find the counter examples by selecting the Browse tab and navigating to Hardware Input and Output>>DAQmx>>Counter Measurements; then you can select the Position category (shown below) to find the Position measurement examples.
Let us know if you have any other questions about taking position measurements.

Adusting video input signal while capturing???

Hello
I'm running Final Cut HD and am having trouble adjusting my video input signal. Under "Clip Settings" in the Capture Tool there appear to be controls, but they are disabled and my scopes do not appear to be reading either.
Any thoughts on how to unlock these controls?
Thank you,
Bryan

You can only adjust video levels if you capture component or SDI with a capture card.
And Zeb, when people say FCP HD more often than not they mean the latest version. I know that FCP 4.5 was dubbed that, but people still hold onto that name.

How to seperate two input signals

Hi people, currently i have one input voltage signal, i would like to add another input signal which display the temp from my Arduino IDE wirelessly via serial visa configure. After doing that, i would like seperate these two signals by using data bits. Can anyone explain to me in a detailed procedures?
i will upload up the file to show the current program that i am having now. One would be the main, the other would be the SubVI file.

I can't tell you anything because you haven't shown me anything of what you are doing.
Show the subVI you've created. How are you merging them together? What does the data stream from your Arduino look like? Once we know that, then it will be easy to figure out how to split them apart.
I wouldn't go so far to see you have a temp waveform and a voltage waveform. It looks like you are just reading them a datapoint at a time. You almost always need to have a Serial Configure when dealing with serial ports. It doesn't matter whether you are reading both datapoints through the same serial port or just one datapoing through the serial port.
