Daqm909A Dc/Ac Coupling Verification (Optional) - Keysight Technologies DAQ970A Service Manual

DAQM909A DC/AC Coupling Verification (Optional)

This procedure is used to verify the basic functionalities of the DAQM909A
4-Channel Digitizer module. Self Test and Autocalibration covers most
functionalities except for DC/AC coupling mode which exercises on board relays
at specified channel under test. The subsequent procedures are designed to verify
the functionality of the DC/AC coupling relays at each channel. This test is
optional.
1 Connect all input channels (Channel 1 to 4) in parallel to a DC Voltage source
2 Perform Full Self-Test using either methods below:
