I am needing to read the frequency of a TTL signal as part of a data acquisition program that also records analog voltage (at 6 kHz). I've looked at the shipping examples for Counter - Read Frequency... etc. but none of them provide a waveform output that would give me time measurements. I'm wondering if it is possible to do this? The only way I can see to do this is to run in "On-demand" mode and take a time measurement when writing to a TDMS file, but this is too slow for my application. I would like to be able to run in "Continuous" mode and obtain time values for all the elements that are read in that "block" of samples. I'm using a 9402 module and generating input TTL signals with a USB-6341.
