Hello fellow LabVIEWers,
I have a problem in understanding the expression "switching frequency" in the spec of the NI 9401.
If I use all eight kanals for inputs, it is stated that the switching frequency will be down to 9 MHz.
So does this mean that I can not use the DIs in a SCTL running on 40 MHz, or does it rather mean that I won't be able to measure frequencies exceeding 9 MHz but still get an input corresponding to every singel channel on every tick, even though it might be still high when the input is allready low?
I'm using a cRIO-9074, and my incoming TTL signal is in the range of 10 kHz. I need this extream oversampling to optain a good accuracy. without using a two counter method.
Thanks!
