I have a USB-6281, and I am attempting to use it to timetag the pulses from an excelitas APD. However, when I attempt to use a counter with an 80 MHz time base to measure the period between each pulse (one counter), the error -200141 is thrown. If I try to do the same task for 2 counters high frequency, the error is also thrown if the measurement time is less than around 5 microseconds. I am wondering if there is some way around this error? Thanks?
