sample to read with sample rate 100khz

Hi

 

I would like to do a continuous acquisition of 32 channels. I want to do this acquisition with a sample rate at 100kHz

But have to know the sample to read. I tried with 1k, 2, 5k, 20k, 50k and I always the same message which says that my data are no available because my data was overwritten.

If someone can tell me what can I put like value for the sample to read, it will be very useful for me.

 

My card ; Ni pxi 6115, min rate sample = 20kS/S, max rate sample= 10Ms/s , inpuit fifo buffer= 32Ms

 

Thank you very much

Hi Romaric,

 

Please share your source code to have a better idea about the system and to identify the root cause of the error.

Hello Romaric,

 

I check here your code is working fine. In your code no wrong steps.

 

I hope you are doing some mistakes for debugging purpose like you have some proves in your acquisition loop or you run your code in high light execution mode. I suggest you remove your all proves and highlight execution if these are there and then run your code. it will work

Thanks and Regards

You may not have any (probes).

 

 He was refering to the use of the LabVIEW diagnostic feature where you right click on a wire and select "Probe" from the menu.

 

This allows you to see the value of the wire when it executes.

 

There is a slight delay caused when you "probe" a wire. This could cause problems in time sensitive applications.

 

 

Your application is missing the file: Log_Channels.
