3.3.12 MEAS Key (Measurement)
3-52
X dB Left
Moves Normal marker leftwards to an intersection point on the
trace X dB down from the present location.
X dB Right
Moves Normal marker rightwards to an intersection point on the
trace X dB down from the present location.
Peak X dB Down
Searches for the highest peak within the target range and displays
Normal and Delta markers on an intersection point on the trace X
dB down from the present location.
The reference marker is displayed at the highest peak point.
Disp Mode REL/ABS.L/ABS.R
Selects how the marker data is displayed.
REL:
The normal marker is displayed on the right; and the
delta marker, on the left.
ABS.L:
The marker on the left is displayed as an absolute value.
ABS.R: The marker on the right is displayed as an absolute val-
ue.

Toggles the continuous X-dB down function on or off.
ON:
Repeatedly executes the X-dB down function from the
highest peak on the trace for each sweep.

Reference Marker ON/OFF
Toggles the reference marker function on or off.
ON:
Displays the reference marker on the X-dB down refer-
ence position

Normal marker on the peak of the third order intermodulation dis-
tortion.
% AM Measure
Calculates an AM modulation factor using a peak search, and dis-
plays the result in percentage (%).
