into memory. The trace in memory will be
refreshed in the next sweep once you press this
softkey. There are three trace refresh mode for
your selection:
Data Only the activated trace is viewable. The
trace memory is not viewable.

Disp Mode
Key access: [Meas] > {Disp Mode}
This softkey allows you to set the Y axis of the
graticule as return loss, VSWR or reflection
coefficient value.
IIM On/Off
Key access: [Meas] > {IIM}
This softkey toggles IIM between on and off. When
there is a need to measure the antenna feed line in
field, there are probably some interference signals
coupled into the device, which will be detected as
spurs in the measurement result. When IIM is set
to on, the analyzer will compensate those spurs by
IIM algorithm.
