Figure 4-75 Status indication for the traces in which scalar-mixer is valid
NOTE
In scalar-mixer calibration, the normal calibration coefficient is invalid while the
frequency-offset sweep is in progress; in this case the scalar-mixer calibration coefficient is
used instead. Turning the frequency-offset sweep (
Frequency Offset
)
OFF
switches over
to the normal calibration coefficient; however, the information on the scalar-mixer
calibration coefficient is retained.
Operational Procedure (when using mechanical calibration kit)
NOTE
Before starting scalar-mixer calibration, verify that the frequency-offset (
Frequency
Offset
) is
ON
. If the frequency-offset is not valid, you cannot start scalar-mixer calibration.
Step 1. Press or to select the channel you want to calibrate.
