RSA3408B Analyzer Service Manual
The auto performance verification and calibration need flatness floppy disks for
the signal generators (Items 1, 2, and 3). The following procedure measures
flatness correction data for the specified signal generator and saves the data to a
floppy disk.
You must create or update the flatness 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 you change the N-N cable
H
When you change the RF attenuator
H
When one year has elapsed from the last update of the file for the generator
STOP
. Select either of these two procedures, depending on the signal genera-
tor(s) you use:
H
Procedure 1 on page 4--7:
Uses one signal generator, Item 3, which covers all measurement bands:
Baseband, RF1, RF2, and RF3.
H
Procedure 2 on page 4--10:
Uses two signal generators: Item 1, which covers the baseband and
RF1 band, and Item 2, which covers the RF2 and RF3 bands.
