Basic Functional Check
The functional check consists of checking the VXI-1200 power supply
voltages to the VXIbus limits at the rear-panel connector J415 using a
digital voltmeter.
Referring to Table 3-5, connect one lead of the voltmeter to a supply
pin at J415. Connect the reference lead of the voltmeter to one of the
ground pins. Compare each voltage reading to the values listed in
Table 3-5.
