and PEAKSEARCH Places a marker on the highest
PEAK SEARCH
point on a trace. The frequency and amplitude of the
marker are displayed in the upper-right corner of the
screen; PEAK SEARCH does not alter the active
function.
The trace must meet the criterion set by the marker
threshold function in order for a peak to be found. If no
peak is found and no marker is active, the marker will
be placed on the trace at center screen. If no peak is
found and a marker is active, the marker position will
not change.

PEAK SEARCH
Sets the minimum amplitude level from which a peak
PEAK THRESHLD
on the trace can be detected. This function places a
dashed line across the graticule to denote the selected
level. To enter a value, use the data keys, the step keys,
or the knob and terminate the entry with
−dBm
Any portion of a peak that falls below the peak
threshold is also used to satisfy the peak excursion
criteria. For example, when the peak excursion is equal
to 6 dB, a peak that is equal to 3 dB above the threshold
will be found if the peak extends an additional 3 dB or
more below the threshold.
Front-panel key access:
Plots only the annotation (excluding the menu, trace
PLOT ANNOT
markers, and error codes). When PLOT ANNOT is
active, STOP ANNOT appears in its place, allowing you
to stop the plot before it is finished. If the annotation is
turned off, no output will be plotted.
Front-panel key access:
Plots only the graticule. When PLOT GRATICUL is
PLOT GRATICUL
active, STOP GRATICUL appears in its place, allowing
you to stop the plot before it is finished. If the graticule
is turned off, no output will be plotted.
Front-panel key access:
PLOT ORG DSP GRAT
(GRAT) origin mode. Agilent Technologies plotters
allow the user to define the size of the plot using P1 and
P2 parameters. P1 defines the lower-left corner of the
plot, while P2 defines the upper-right corner.
