Hi Evie,
To measure frequency with SignalExpress using your USB-6501
- Add a DAQmx Acquire->Analog Input step, put your digital input into the analog input you pick, set the sampling rate to be atleast 2-10x the input signal rate.
- Add the Timing and Transition step
- Run the VI
- Observe the frequency.
