Adjustment Procedures
RSA3408B Analyzer Service Manual
4- 13
The auto performance verification and calibration need the spurious floppy disks
for the signal generators (Items 1, 2, and 3). The following procedures measure
the spurious correction data for the specified signal generator and saves the data
to a floppy disk.
You must create or update the spurious correction file when one of these
conditions is met:
H
When you calibrate the analyzer initially
H
When you calibrate the signal generator
H
When you change the signal generator
H
When one year has elapsed from the last update of the file for the generator
NOTE
. Store the spurious correction file on the same floppy disk (Item 17) as the
flatness correction file for the signal generator.
