Note: To troubleshoot the readback DAC from the front panel if the unit has failed selftest, place jumper A8J5 in the skip selftest position (see Table
Use the front panel controls to vary the output voltage from zero to
To check the multiplexer, use the front panel controls to obtain the waveforms at the output of the multiplexer
If the waveforms are not correct, use the front panel controls and a DMM to check the multiplexer input voltages at the following nodes:
