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:
{numeric 1}: Value of Z
r
(resonant impedance).
{numeric 2}: Value of f
r
(resonant frequency).
{numeric 3}: Value of Z
a
(anti-resonant impedance).
{numeric 4}: Value of f
a
(anti-resonant frequency).
{numeric 5}: Rpl
1
(the maximum value of the left-side ripple (the sweep parameter
difference between the peak and the left adjacent negative peak)
within the range to the left of the resonant point within the waveform
analysis range).
{numeric 6}: Value of Rpl
2
(the maximum value of the right ripple (the sweep
parameter difference between the peak and the right adjacent negative
peak) within the range between the resonant point and the
anti-resonant point within the waveform analysis range).
{numeric 7}: Rpl
3
(the maximum value of the left-side ripple within the range to the
right of the resonant point within the waveform analysis range).
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
r
, f
r
,
and Rpl
1
. If no phase 0° point is detected, 0 is read out for all the parameters.
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.
