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

PKPOL {POS|NEG}

PEAK DEF: DX

Sets DX of the peak slope

DY/DX, one of the peak definition items for

executing peak search for the current active trace (A or B). If the peak slope

DY/DX is set in the peak definition, peaks that have a slope greater than this

slope are detected in peak search.

PKDLTX <value>

PEAK DEF: DYSets DY of the peak slope DY/DX, one of the peak definition items for executing

peak search for the current active trace (A or B). If the peak slope

DY/DX is set

in the peak definition, peaks that have a slope greater than this slope are detected

in peak search.

PKDLTY <value>

MKR ® PEAK DELTA

Substitutes the peak slope

at the position of the main marker on the current

active trace (A or B) into the peak slope DY/DX as the peak definition used for

peak search. In other words, peaks that have a slope greater than the peak at the

current marker position 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.
