Hello AutoTec,
You do not need to connect an external source to your
counter. There are a few counter examples
that are shipped with LabVIEW and will measure a digital frequency. (Hardware
Input and Output >> DAQmx >> Counter Measurements >> Digital
Frequency >> Meas Dig Frequency-Low Freq 1Ctr.vi) Connect your signal (10Hz signal) to the gate
(Pin 32 or PFI 1) on the counter.
Pin 32 can be used for a PFI line, P0.1 digital input line
or a counter gate line. If you use this
pin for your counter application, you can not use as a PFI or digital line.
Respectfully,
