2-6 Calibration
The following symbols and indicators indicate the instrument status or
condition on the display.
Calibration Symbols
The current calibration status and type is displayed in the upper-left of the
screen when in Cable-Antenna Analyzer mode. The three status messages
are described next.
Cal Status OK (Cal Type)
The Microwave Site Master has a valid calibration being applied. It is not
possible to change the frequency range after calibration without performing
another calibration. Note that the CALIBRATION OFF message can indicate
different calibration conditions.
Cal Status --
The Site Master has not yet been calibrated (–). Perform a calibration before
making measurements.
Cal Status OFF
The Site Master has been calibrated, but Cal Correction is Off (OFF). The
calibration correction has been turned Off by the user or by the recalled
setup. Set the Cal Correction to On, or start a new calibration.
Cal Status OFF
The Site Master has been calibrated, but the instrument temperature has
drifted more than ±10 ºC since the last valid calibration was performed (ºC).
A new calibration is required.
For calibration procedures refer to Chapter 4.
