OUTPRESR?
Syntax
OUTPRESR?
Description If the sweep parameter is frequency and the measurement parameter is |Z|-θ, within the
waveform analysis range specified with the "ANARANG" command on page 267,
analyzes the resonant point and ripple, and reads out the result. If the sweep parameter is
not frequency or if the measurement parameter is not |Z|-θ, executing this command causes
an error and all readouts are 0. (Query only)

The readouts are as follows:

This command searches for phase 0° points within the analysis range from the left edge,
and defines the 1st detected point as the resonant point and the 2nd detected point as the
anti-resonant point. Even if 3 or more phase 0° points are detected, only the first 2 points
are used. If only 1 phase 0° point is detected, 0 is read out for parameters other than Z
and Rpl
The peak and negative peak used at the execution of this command satisfies the condition
set with the "THRR" command on page 452. They are not related to the peak definition in
the marker search function.
