Hi,
I've been examining the digital output pulse from P0.0 on the PXIe-6124 and noticed a difference in amplitude when measured on an Oscope vs on the PXIe-6124's Analog Input. The pulse measured on the Oscope has a 5vdc amplitude referenced to ground. That same pulse measured on the PXIe-6124's Analog Input is about 2.7vdc in amplitude with the low side at around -10.2vdc and the high side around -7.5vdc.
After that said, my concern is I'm using this P0.0 pulse to drive a solid state relay with a minimum turn-on level of 3.5vdc. I trust the output level of the external scope, but a little doubt is in my mind do to the difference in the amplitude levels measured. I'm just curious about the difference.
Tks, Terry
