Can I input a square wave using 6534 DIO card?
I'm trying to read in a square wave using the
6534 DIO card. It seems like a easy enough task.
But I not having any luck yet. Any helpful hint
from experienced user? I'm using an HP square wave
generator.

Thank you,
Van

what you need is the example for digital input.
at high enough speed and enough samples to see the voltage swing.
the output of the waveformgen should be between 0 and 0.4 volt to see a zero and above 1.8 volt to see a 1.
normally on a scope you see plus and minus but here you have ttl like inputs.

Thanks again Albert.
I will try this.
