Adjustment Procedures
This chapter contains an adjustment procedure for your instrument. The purpose
of this procedure is to return the instrument conformance to its specifications.
Adjustment Interval
The voltage and timing references inside the instrument are very stable over time
and should not need routine adjustment. The only time you should perform the
Adjustment Procedures is if the instrument fails any of the mainframe perfor-
mance verification checks provided in the DSA8200 Specifications and
Performance Verification manual.
Adjustment Environment
The instrument must be adjusted in a 20
°
C to 30
°
C ambient temperature
environment. The instrument and signal source must warm up at least 20 minutes
in this environment before you begin the adjustment procedure.
Adjustment After Repair
After removal and replacement of a module due to electrical failure, you must
either perform the adjustment procedure or not, depending on the module
replaced. See Table 3--1.
