EndReadMultiSampleDouble in c# (Pci6602,Period Measurement)

[koins]

Hello,

If I choose a high number of samples in BeginReadMultiSampleDouble always get a timeout while reading with EndReadMultiSampleDouble. What's the condition that a timeout occurs ?

Thanks andré

Hi koins,

the condition refers to your sample rate.

If you choose e.g. a sample rate of 1kHz and your number of samples is 1000, than ONE measurement iteration will take 1 second.

If you set the sample rate to 1kHz and the number of samples to 10000, than ONE measurement iteration will take 10seconds.

If you want to use a very high number of samples, you should increase the timeout.

You can calculate the time which is needed by:

time for ONE iteration = (number of samples) / (sampe rate) 

This is because we are using a Fifo memory and we transfer the data in blocks (number of samples) from the device to e.g. Labview, C#, C++,... 

Hope this helps

Best regards
