To check probe power outputs
Probe power outputs are on the front panel, surrounding each BNC input.
Any failure may be a problem with the probe power and control assembly, the AutoProbe flex
cable, the probe power and control cable, or the power board.
Use the table and figure to the right
to check the power output at the
connectors.
The +12 V and –12 V supplies
come from ripple regulator on
the power board, and the +3 V
and –3 V supplies are
developed in three-terminal
regulators on the probe power
and control assembly.
Measure the voltages with respect
to the ground terminal on the front
panel, located near the Aux Out
BNC.
Do not attempt to measure voltages
at pins 3 through 7.
