2715 Spectrum Analyzer Service Manual 4-1
Performance Verification
This section contains proceduresfor verifying that the instrument performs
according to the characteristics stated in t hePerformance Requirement columns
in Section 1: Specifications.
If a failure is found, it is recommendedthat only those circuits that do not meet
performance criteriabe adjusted. If adjustment fails to return the circuit to
specified performance, refer to Section 6: Maintenance for repair procedures .
A procedure that is unique to instrumentoptions is described as a subpart of the
step, where practical, or at th e end of this section.

Incoming Inspection Test

The User manual contains a system checkout (powerup check) of the Spectrum
Analyzer. This check is recommended for incoming in spections because it
requires no externalequipment or special experience and is a reliable indication
that the instrument is performingproperly.

Verification of Tolerance Values

Tests shall be performedonly after the normalizations have occurred. If a test
should fail, normalize the instrument by pressing UTIL3 0. The normalization
will correct for anychanges in the operating environment due to time or
temperature.
Measurement toleranceof test equipment should be negligible in comparison to
the specification being tested. If not, the error of the measuringapparatus must
be added to the specification tolerance.

History Information

Corrections or additional informationis included when revisions are made to the
manual. If modifications require changesin the procedures, information applicable
to earlier instruments will beincluded within a step or as a subpart to a step.
