Introduction - Agilent Technologies 8564EC Service Manual

Introduction

Automated adjustment and diagnostic software is required to provide
some of the spectrum analyzer adjustments. The software also provides
automated diagnostics for troubleshooting. Instructions for using these
programs are included in this chapter. The 8564E/8565E
Adjustment/Diagnostic Software is essential for proper adjustment of
an 8564EC or 8565EC spectrum analyzer.
Never perform adjustments as routine maintenance. Adjustments
should be performed after a repair or performance test failure. For
information on which adjustments to perform, see
Where both a manual and an automated adjustment number are shown
for a given adjustment, either the manual OR the automated
adjustment may be performed.
Some of the adjustments must be done manually. The manual
adjustment procedures can be found in Chapter 3 of this service guide.
The following lists identify all of the automated and manual
