In the following procedure, it is necessary to probe voltages
which, if contacted, could cause serious personal injury. Use
a nonmetallic alignment tool when making adjustments. Be
extremely careful.
Do not attempt to measure the CRT filament voltage directly. The
filament voltage is referenced to the high-voltage cathode and
can only be measured safely with a special high-voltage true-rms
voltmeter and probe.
1. Set the spectrum analyzer LINE switch to STANDBY.
2. Remove the top cover from the IF-Display Section and connect
the equipment as shown in Figure 3-12.

3. Set the DVM to the
1OOV
range, and connect the DVM to
AlA7TP3 (+ 120V) without the high-voltage probe. See
Figure 3-13.
Note
The accuracy of the high-voltage probe is specified for a probe
connected to a dc voltmeter with 10 MO input resistance. HP 3456A
and HP 3455A digital voltmeters have a 10 MO input resistance on the
100 V and 1000 V ranges. All measurements in this procedure should
be performed with the DVM manually set to the 100 V range
(kOO.000
on the HP 3456A display).
