Change 5622 sampling frequency

Hi,
I am working on a PXI project to generate a single tone frequency signal, (which will be modulated by vital signs) and then demodulate the signal and view the time domain demodulated signal and its spectrum. I am able to generate the signal and view the demodulated wave but the problem is I am using PXI 5663 for the receiver (and 56773 to transmit the single tone signal) and the 5622 digitizer has a very high sampling rate(150MS/s) which is too high for vital signs (whose frequency is not more than 10-12Hz).
I want to change the sampling rate of 5622 and I read a couple of sites (http://zone.ni.com/reference/en-XX/help/370592P-01/digitizers/5622_clocking/) and documents on
I am using PXI Clock as the Reference Clock Source to synchronize the 5673 and 5663 so how can I change the clock frequency of 5622?
I tried using the Decimate and Resample vi s to change the sampling frequency of the received waveform but I did not get any output.(Please find attached the vi and the front panel description of the demodulate vi;the transmission vi is the default RFSG Single Tone Generation).
I am stuck at this point and don't know how to proceed.
Could someone please help me out?
Thanks so much,
Sharmi

Bessel low pass filter and sampling frequency

I have a 20 kHz sine wave signal, use the Bessel LowPass filter.
The input parameters for the filter are as followings: sampling freq: 204800, Order: 8, low cutoff freq: 30000.
The filtered X has a much lower amplitudue compared to to the input signal.
If I change the sampling frequency to 80000, it seems the filtered X is better.
Can you please explain the behavior of the filter?

Thank you for the reply!
I attached a test vi, which generates a sine wave and calculate its RMS (basic DC/RMS). The sine wave is then passed to a low pass filter, a new RMS is calculated from the filtered signal.
Test case 1:
Frequency = 10 kHz, Amplitude = 4, Sampling Info: Fs = 80 k, #s = 1000; Low pass cutoff frequency = 30 k; Filter sampling frequency = 80k.
The signal RMS = 2.8284; Filtered signal RMS = 2.71.
Test case 2:
Same setup as case 1, change the Filter sampling frequency to 204800.
The signal RMS = 2.8284; Filtered signal RMS = 2.4688.
Test case 3:
Frequency = 20 kHz, Amplitude = 4, Sampling Info: Fs = 80 k, #s = 8000; Low pass cutoff frequency = 30 k; Filter sampling frequency = 80k.
The signal RMS = 2.8284; Filtered signal RMS = 2.21.
Test case 4:
same setup as case 3, change the sampling frequency to 204800.
The signal RMS = 2.8284; Filtered signal RMS = 1.5369
Can you please why increasing the sampling frequency will get lower RMS value?
Thanks.

Gain changes on sample rate change

I wrote an application with 2 channel analog input with different gains. If I change the sample frequency the gain setting seems to mix up. But the sample frequencies work if used as first. So, only after changing the sampling frequency the gains are mixed and could not be 'reset' by calling Scan_Setup() from NIDAQ library again.
Any ideas?

Hello,
So it seems that changing the sampling frequency is affecting the gain of a channel?
I am not that sure what is causing this behavior, if you could answer the following questions, we could begin to figure this one out.
1.) How do we know that the gains are mixed up? Is one signal significantly larger then before? Is the code width decreased?
2.) Are you trying to change the sampling rate during acquisition? Are you running the acquisition to the end, then calling Scan_Setup again?
3.) Do you get this error if you call DAQ_Clear before reconfiguring the sampling rate?
Also, if you could post some pseudo code that explains which DAQ calls you are making, and their order, we should be able to get this problem figured out.

IPhone: AudioQueue - is it possible to change the sample rate?

I've been playing around with the AudioQueue stuff for a few days and it's all working fine.
I was trying to build a low-latency playback system by making the streaming buffers the same size as the audio file and pre-loading the buffers (which works fine) but I've hit a snag.
I've been trying to get the streaming to work at different sample rates so that I can play back the same sample at different pitches. I managed to do it by modifying the sample rate in the AudioStreamBasicDescription structure but in order to actually make the stream playback at the new rate it seems you have to create a new output, reload the audio file into the buffers and re-enqueue the output queue before starting playback again, otherwise the sample rate change has no effect.
There is a method to set queue properties; AudoQueueSetProperty() but unfortunately the sample rate Property (kAudioQueueDeviceProperty_SampleRate) is read-only
Can anyone suggest a way to achieve this with AudioQueue or do I need to move over to OpenAL?
Thanks,
Neil

Dan,
there is one point in your understanding, which i am not sure what you think about when talking about it: I understand E-series devices do not support this property change while the VI is running.
infact, you cannot change the sample clock rate during acquisition. but
this does not mean that you cannot change it while the VI is running.
you have only to interrupt the acquisition. since you want to acquire
continuous, this would have the same effect as stopping the vi, i asume.
so the best way to accomplish this task is to use an external clock.
this is e.g. often used for acquistion on rotating shafts. the
acquistionrate is always e.g. 24 points per revolution regardless of
the rotational speed of the shaft, except for a maximum frequency of
course.

How to lock sampling frequency for 5673 and 5663

Hello,
In general I'm trying to lock transmitter and receiver together. It seems easy to lock the carrier frequency, however no matter what I do, I seem to have a drift in my sampling frequency (on the order of 1ppm).
Is the sampling clock in the 5663 digitizer tied to the same clock reference as the LO? ... I didn't think I would need the TClk mechanism here since I don't care about delay ...
Any thoughts are greatly apreciated. Below are a few specifics.
I'm using the 5673 as transitter and 5663 as receiver. I've noticed the folowing:
1. When each are using a 'Reference Clock Source' = OnboardClock I have a noticeable carrier offset at the receiver (eg 5.8 GHz carrier has ~7 KHz offset) and this is fine.
2. When each are using a 'Reference Clock Source' = PXI Clock, with the chassis physically tied, I see no noticeable carrier offset at the receiver.
3. When 5673 is using 'Reference Clock Source' = OnboardClock, 5663 using 'Reference Clock Source' = ClkIn (ClkIn/Out physically tied), I see no noticeable carrier offset at the receiver.
Solved!
Go to Solution.

Hi Clayton,
The digitizer sample clock time base source is different from the Reference Clock source. I've copied a description below of the difference between the two from the digitizers help.
Clocking:Reference (Input) Clock Source:
Specifies the input source for the PLL reference clock.
Clocking: Sample Clock Timebase Source:
Specifies the source of the sample clock timebase, which is the timebase used to control waveform sampling.
Yes, the default configuration of the NI 5663 is for the NI 5652 to export its internal 10 MHz reference to the NI 5622 so that the NI 5622 and the NI 5652 devices are frequency-locked. The NI 5663 can also be configured to lock to an external (10MHz only) reference source. The NI 5663 can also be configured to lock to the PXI 10 MHz backplane clock. Locking to the PXI 10 MHz reference does not require a cable, but this configuration does not provide the same frequency and phase noise performance as the NI 5652 internal Reference clock. All of this information is provided in detail in the NI RF VSA Help. See the directory below:

Sampling frequency in timed loop

Hi Guys. I used timed loop, is it my current sampling frequency from Figure 1 is 10kHz? if I want to change for example to 2.5kHz, should I just change 100 constant to 400?
Thank you.

mikeporter wrote:
Then, yes you are correct, but you have a problem in the form of those two express VIs. The way the code is written, the analog input and analog outptput tasks will be opened and closed with every iteration.
Sorry Mike, but that is wrong. We are dealing with a myRIO here, which behaves exactly the same as a cRIO. The IO is directly off of an FPGA. There is no task to open and close.
Though, I would question the actual sample rate. If the scan engine is being used, then the channels are actually sampled more like 100Hz. Please attach your entire project (put it into a zip file first) so we can get a little more insight to how things are set up.

How to adjust line sampling frequency in photoshop CC on surface pro 3

I just got a Surface Pro 3 so that I could work on my art on the go. I am used to working on a mac with a cintiq, but fell for the hype that photoshop was optimized to work with SP3. However, when I try to use the brush tool, my lines look AWFUL! no matter what I do, the lines are wavy and messy looking. I read that PSCC raised the sampling frequency rate so that the line would look better, but I think THAT is exactly why it looks awful. the Surface pro seems to be picking up EVERY microscopic twitch. I cant work like this ... and I am surely not the only person using PSCC on the SP3, as they're ADVERTISED to work together. How do I adjust the sampling frequency so that my line looks as smooth as it does on a Wacom in photoshop? ...because THAT image below.. looks like crap.

I'm not an artist so I don't draw using my Surface pro 3. Many have the same issue with wacom tablets and cintigu from what I read. They seem to be able to solve their concerns by installing a plugin Lazy Nezumi Pro - Mouse and Pen Smoothing for PhotoShop and other Apps Remember I don't draw and have not installed that plug-in so I can not state that it works well on a surface pro 3.
Doing a Web search I found this I quote
Hi guys,
I'm the author of Lazy Nezumi Pro!
Here's the situation with the Surface Pro 3: I'm not 100% sure, but I think the people who got LNP to work with the SP3 the ones who have Photoshop CC 2014, which uses the new Windows 8 native tablet API (instead of Wintab, which is very old tech). If you have this version, make sure you enable Windows Ink for it to work right. It's possible that the N-Trig Wintab implementation is just buggy, or that it's doing something very differently than what LNP is expecting (this is probably the case since I have reports that PS works fine without LNP). Unfortunately I won't know more until I get a SP3 myself and do some testing/debugging.
I'm sorry I can't help more right now, but I'll keep you updated!

PCI-6023E DAQ card maximum sampling frequency

Hello
I am using PCI-6023E DAQ card in pc-based ETS solution (and writing appilication in LabView 7.1 with RT module). The card has 200kS/s maximum sampling frequency, but it can be set for much higher sampling frequencies and the waveform acquired appears to be correct (i.e. i've tried setting it fo 1MS/s and sampling 400kHz sine, which is obviously above Nyquist frequency for 200kS/s card, but on spectral graph, main peak is at 400kHz). Is the card driver doing some kind of free/coherent sampling?
Moreover, when sampling frequency is set to 200kS/s, the card seems to be doing same thing - i.e. for 200kS/s and sample block size of 200kS, graph should be updated once in a second, but it's updating slighty slower.
I'd really appreciate if someone could explain me (or gave me a link to materials) what exactly is happening here? Is driver doing some background work, or maybe it is problem with network latency/unstability ? What is the impact of this effect on real-time aquisition?
Thanks in advance
Jan Kienig

Since the fundemental is 4 times the nyquist, then what you are measuring is an alias of the fundemental. This works well as long as the fundemental is a repetitive signal. Sampling every other peak and every other node looks the same as sampling every peak and node. Tektronix exploited this on their 7S series sampling heads. Another use of this phenomena is the effective demodulation of high frequency signals as long as the bandwidth meets nyquist. As with your card, if the input amplifier supported it, I could extract modulation information from a 500 MHz signal so long as the the bandwith of that modulation did not exceed 100 kHz.

What are supported sampling frequency and digitization rates for Zen Micropho

Some MP3's are playing back slowly. It is inconsistent, though, since files with the same digitization rate and sampling frequency will behave differently - some right speed, some slow.
The bulletin board says:
"My tracks don't play at the correct speed e.g. they play too slowly, why?
Chances are they are encoded in an unsupported sampling frequency..."
How do I find out what the supported sampling fequencies and digitization rates are?

Thanks for the info. I guess I was looking for something more specific - the exact bitrates and sample rates that Creative claims to support. Would you know where official and comprehensi've data can be had? There must be a tech spec somewhere.
It is common these days in business to see a recording of, say, a conference call or seminar presentation at 32k bitrate/025Hz, or even 24k bitrate/8000Hz, posted to a company's website for download by those who could not be there, and MP3 players are increasingly used for their replay. Companies use low digitization rates because there is no need for hifi and the files are much smaller: less storage, faster download.
I'd be surprized to think that Creative don't have compatibility with the standard range of rates offered by ubiquitous programs like Audacity and dBpower, the latter being one they themselves recommend!

How can I change the sample rate (delta X)?

Hi, I create vi which can measure resistance, it will record the data and write to a file.
however, I want to change the sample rate which is delta x. is that anyway I can do?
I have try to put a clock inside the loop, it does slow down the speed but not the sampling rate.
Please help me!!
Thank you!

Hello Shan405,
Adjusting the Reading Rate of a DMM
As noted in the above DeveloperZone article, there are a lot of factors contributing to a reading rate of a DMM. 'Sampling rate' can only be configured in digitizer mode, which can only be achieved on the flex DMMs

Sampling frequency Fs and number of sample #s in a waveform

Hi there,
It is probably a stupid question but I am still going to ask it:
I do not completely understand why in the "Basic Function Generator.vi" there is a distinction between the number of samples #s and the sampling frequency Fs..?
What is the purpose to have more or less samples in the generated waveform then specified by the sampling frequency of the signal?
I hope this question make sense (or am I missing something obvious)?
thanks,
Best,
Renaud

I am sending those values to an AO (to a mechanical system that reproduce the sended waveform) and record the signal with an AI. My problem is that when I reduce the number of sample as explained in the previous message, I enhance the number of cycles i.e the time of the signal seen by the AO but it does not seem to apply to the AI... see attached image (Fs = 305000 #s=30500 AO is in white AI is in red)
Why does the #s only affect the time of AO and not the one of AI? (the number of cycle is the same though, only the time base is different)
I think we need to see some code in order to get the full picture of what you are doing. The number of samples of the AO should have nothing to do with the AI.

Dynamically changing the sample rate

hello!
usually we can't dynamically change the sample clock when the program is running.So I want to ask how to dynamically changethe sample rate when program is running,Can you give me a example?
Thank you!

I think there is no such example.
But i think you could add a while loop structure outside your main program. In the front panel, add a button named change sampling rate, when you press the button, the program stops the present acquisition and into a new acquisition configuration and start acquisition.

Sample Frequency of Low Pass filter VI is ambiguous

I am having trouble understanding how the Sampling Frequency of the Low Pass Filter actually impacts the function buried within. The information passed in is an array with no relavance to time. How does the function actually sample this array of data at a frequency?

I doubt that they actually build a waveform. Here is my guess: By defining a sample frequency they can get the sampling interval dt as you indicated. By defining a sampling frequency the cutoff frequencies can be scaled to frequency units (Hz), making the VI easier to use.
