1. If COMPLEX Z-Y has been selected as the measurement parameter, this is the primary measurement parameter value. The
primary measurement parameter value means: if COMPLEX has been selected as the display format, the value of the real part (R
or G) of each complex parameter; if POLAR, the absolute value (|Z| or |Y|) of each complex parameter.
2. The amplitude of peaks means: amplitude of crests (parts that protrude in the waveform in the increasing direction of the
measurement parameter value) if the peak polarity is defined as positive; amplitude of troughs (parts that protrude in the
waveform in the decreasing direction of the measurement parameter value) if negative.

PEAK PLRTY [ ] For the current active trace (A or B), selects positive [POS] or negative [NEG] to
define the polarity of peaks for peak search. If the peak polarity is set to positive
[POS], peaks are parts (crests) that protrude in the waveform in the increasing
direction of the measurement parameter value

; if negative [NEG], parts
(troughs) that protrude in the waveform in the decreasing direction of the
measurement parameter value

D Y/ D X is set in the peak definition, peaks that have a slope greater than this
slope are detected in peak search.

1. If COMPLEX Z-Y has been selected as the measurement parameter, this is the primary measurement parameter value. The
primary measurement parameter value means: if COMPLEX has been selected as the display format, the value of the real part (R
or G) of each complex parameter; if POLAR, the absolute value (|Z| or |Y|) of each complex parameter.
2. The peak slope means, on the plane whose vertical axis is the measurement parameter value and whose horizontal axis is the
sweep parameter value, the absolute value of the smaller slope: a slope of the line connecting the peak measurement point and
the next left measurement point or a slope of the line connecting the peak measurement point and the next right measurement
point. It indicates the sharpness of the peak. Note that if COMPLEX Z-Y has been selected as the measurement parameter, this
definition can be applied, assuming a plane whose vertical axis is the primary measurement parameter value and whose
horizontal axis is the sweep parameter value.
