Hello,
I am trying to measure voltage with NI9205 and cRIO NI9030.
I have generated a sinus wave with a GBF, and each time i am changing the frequency.
for frequency between 0 to 100 Hz, it works perfectly and i have no probleme of aquisition but for the frequency supperior than 100 Hz i have probleme of sampling.
I tried to change the frequency sampling of my cRIO but i always have the same probleme.
By the way i am working in scan mode.
Is it the probleme coming from the scan mode ? because i heard that we can improve the sampling frequency in FPGA mode ?
Or maybe the probleme from my VI ?
Your faithfully,
BELAJI

Hi, have you read this KB?
Set Sampling Frequency Using compactRIO Scan Engine
Of course you can improve the rate by using FPGA but
even if you use scan mode, the rate is up to 1kHz.
