Syntax OUTPRESO?
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 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)
Query response {numeric 1},{numeric 2},{numeric 3},{numeric 4}<newline><^END>
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).
This command searches for points of phase 0° 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 both Z
a
and f
a
. If no phase 0°
point is detected, 0 is read out for all the parameters.
