2-6 Calibration Symbols Instrument Overview
2-6 Calibration Symbols
The following symbols and indicators are displayed in the upper left of
the screen to indicate the instrument calibration status and type when
in Cable & Antenna Analyzer mode.
iCal Status OK (RFP1)
The Site Master has been calibrated for an OSL or InstaCal Reflection
(1-port) measurement with a Flex calibration indicating it is possible to
change the frequency range after calibration.
Cal Status OK (RFP1)
The Site Master has been calibrated for an OSL or InstaCal Reflection
(1-port) measurement with a Standard calibration indicating it is not
possible to change the frequency range after calibration without
performing another calibration.
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. 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 however the instrument
temperature has drifted more than ±20 ºC since the last valid
calibration was performed. A new calibration is required. For
calibration procedures, refer to Chapter 7.
Notes
Three calibration methods are supported by the instrument:
RFP1: Full 1-port Reflection (OSL or InstaCal)
TRES: Transmission (using External Sensor)
2PES: Combined Full 1-port Reflection (OSL or InstaCal)
and Transmission (using External Sensor)
Standard or Flex calibration types can be performed with
either the built-in InstaCal module or using external Anritsu
OSL calibration components.
