Presetting the Analyzer: How Calibration Is
Affected
Two-Port Calibration
When the current calibration is a two-port calibration (user-defined or
default) and the instrument is preset:
• a default calibration (not two-port) will be automatically restored, or
• a user-defined calibration (not two-port) will be automatically
retrieved if its settings match those of the instrument’s preset
After instrument preset—how to retrieve a previous user-defined
two-port calibration:
1. Adjust the instrument settings to be compatible with those of the
previous user-defined two-port calibration.
2. Select .
Other Calibrations
When the current user-defined calibration is anything except a user
two-port and the instrument is preset:
• a default calibration will be automatically restored, or
• the current user-defined calibration will be retained if its settings
match those of the instrument’s preset
After instrument preset—how to retrieve a previous user-defined
calibration:
1. Adjust the instrument settings to be compatible with those of the
previous user-defined calibration.
2. Select the softkey of the calibration you want to retrieve.
