Presetting The Analyzer: How Calibration Is Affected - HP 8712ES User Manual

NOTE A two-port calibration (default or user-defined) that is selected on one
measurement channel will automatically be selected on the other
measurement channel, unless the alternate sweep feature has been
selected.
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 User 2-Port
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.
