Calibration status indicators
The instrument displays calibration status that is an important indicator to get reliable and accurate
measurement results from CAA testing. The calibration status includes
ON
,
ON (E)
,
ON (I)
,
ON (Q)
,
OFF (T)
, and
OFF
.

Calibration status indicators
Indicator(s)
Description
ON
Indicates that a mechanical O-S-L calibration is performed using a Y-Cal kit and the
instrument is ready to make a measurement.
ON (E)
Indicates that an electronic O-S-L calibration or e-calibration is performed using VIAVI
EZ-Cal kit and the instrument is ready to make a measurement.
ON (I)
Indicates that the frequency setting is changed within the frequency range registered
for the O-S-L calibration and so the calibration is still valid. When the calibration status
changes from ON to ON (I), re-calibration is not necessarily required.
ON (Q)
Indicates that quick calibration (Quick Cal) is performed. It is useful only if cable length
measurement is needed.
OFF (T)
Indicates that the temperature registered during the calibration is changed by ±10
C or
greater. It is recommended that you perform a new O-S-L calibration to obtain accurate
measurement results. When the temperature comes back within the registered range,
the status may be changed to ON.
OFF
Indicates that the frequency setting is changed off the frequency range registered for
the calibration. The calibration is no longer valid.
