Iam using ni 6341 USB device and using Large frequency counter method to measure frequency from 0hz to 10khz which is varying at 200ms but iam not able to get the data perfectly in the chart as well as while logging the data.The data comes is of 1 s instead of 400ms (200 ms for reaching from 0-10khz and 200ms from 10khz-0).Iam confused as it works for the ramp (0-500hz at 200ms and 500hz-0hz at 200ms).
I have given sweep (square wave) start frquency 0Hz and stop frequency 10kz with sweep time 200ms and return time 200ms from signal generator and also tested this in the oscilloscope but when i tried meassuring with ni usb 6341 the problem was occuring .I have connected to counter 0 of 6341
