Adjustment Procedures
Introduction
Refer to
components used in the instrument along with their functions.
Factory-selected components are identified with an asterisk on the
schematic diagrams.
Adjustment Tools
For adjustments requiring a nonmetallic tuning tool, use fiber tuning
tool, HP part number 8170-0033.
Two different tuning tools may be necessary for IF bandpass
adjustments, depending upon the type of tuning slug used in the
slug-tuned inductors. If the tuning slug requires a slotted tuning tool,
use HP part number 8710-1010. If the tuning slug requires a forked
tuning tool, use HP part number 8710-0772.
Never try to force an adjustment control. This is especially critical
when tuning variable capacitors or slug-tuned inductors. Required
service accessories, with part numbers, are listed under "Service Kit" in
Chapter 1.
Instrument Service Position
Refer to Chapter 3 for information on removing the spectrum analyzer
cover assembly and accessing all internal assemblies.
