Calibration 7-3 Calibration Procedures
The calibration factor can be turned Off with the Cal Correction button.
The calibration coefficients are saved and can be reapplied by setting
Cal Correction back to On.
Temperature Window
Anritsu recommends allowing the instrument to warm up for
~10 minutes to typical operating temperature before calibrating. Any
applied calibration factor will automatically be turned off if the internal
temperature moves outside the valid cal window. The Site Master will
display: and a new cal will be required.
Save and Recall Calibration Coefficients
Calibration information is included when a setup (.stp) file is saved
(even if the Cal Correction is Off). The calibration information is also
recalled with a setup file and can be applied (Calibration > Cal
Correction On) if the current internal instrument temperature is within
the saved cal window.
Calibration information is not included when a measurement (.dat) file
is saved.
Note
The InstaCal module is not a discrete calibration component
and it can not be used at the top of the tower to perform line
sweep measurements.
