3.3 Vpp counter pulse generation

[Simon74]

Hi,

I have a question regarding counter pulse generation with 3.3 Vpp specification.

DAQmxErrChk (DAQmxWriteCtrFreq(pView->SweepRateHandle,1000,0,10.0,DAQmx_Val_GroupByChannel, pView->fUserFrequency, pView->fUserDutyCycle, NULL, NULL));

This function works fine but gives me 5 Vpp pulses.

Is there any function controlling amplitude conversion?

Thanks,

Unfortunatly, the digital levels for almost every device (and every device with Counters that I know of) is determined by the hardware and can't be changed.  The easiest solution would either be a logic level shifter or a voltage divider.
