Adjustments
f . Using a 10: 1 probe, connect the oscilloscope t o the "OSC" test point (A67TP l ) .
The voltages involved in the following measurements may cause
serious injury or death. USE EXTREME CA UT/ON.
g. Turn the 3585A power on. Turn the front panel intensity control fully C . W . Verify
that A67TP l measures approximately 26Vp-p centered + 1 8V above ground potential.
h. Turn the front panel intensity control fully off and verify that the A67TP 1 output
is + 1 8V DC .
i. Disconnect the scope probe.
j . Connect a DVM (200V range) to the l 00V A67TP2. Adjust A67R38 for a reading of
±
l 00V 0.25V.
k. Turn the 3585A power off. Disconnect DVM.
The voltages present inside the high voltage power supply box can
cause serious injury or death.
