Hello guys.
I am using the PXI4464 to perform voltage measurements. On the future, this equipment will be used to take some voltage samples from another device, and it will be enclosed (without access for at least 3 months). Because of that, it is not possible to perform the tests showed in the PXI4464 Calibration Procedure Manual. In this context, I need a system able to verify if the PXI4464 is operating well (without drifts, for example).
One idea was to use a very precise pulse generator, in order to generate a signal that will be read by the PXI4464. Any divergence from the expected value could mean that the equipment is not operating properly.
Do you know any card from NI or another equipment that could be able to generate a very precisely voltage pulse signal? I was wondering how it is possible to check the quality of the measurements in the case that it is not possible to access the equipment.
Thanks folks.
