Key Descriptions
Descriptions are listed alphabetically by the front-panel key or softkey
label.
∆MARKER
OCC BW Calculates the occupied power bandwidth with respect
to the power between the markers, instead of with
respect to the total power in the span. The percent
occupied power is set by the OCCUPIED [ %] softkey.
The markers are moved to positions that indicate the
edges of the occupied power bandwidth. The
OCCUPIED BANDWDTH softkey description has more
information about making occupied power bandwidth
measurements.
The post-measurement menu is then displayed. The
original marker positions are remembered so that the
measurement can be repeated from the
post-measurement menu.
Front-panel key access:
MEAS/USER
# ALT
CHANNELS Allows you to select the number of pairs of alternate
channels to be measured, in addition to the adjacent
channels. Selecting a zero makes the measurement
with the adjacent channel pair, but no alternate
channels. A 1 selects the first alternate channel pair
which is centered at ±2 times the channel spacing away
from the center frequency of the main channel. A 2
selects the second alternate pair which is at ±3 times
the channel spacing.
Front-panel key access:
MEAS/USER
0 → 10V
LO SWP Specifies the 0 to 10 volt ramp that corresponds to the
sweep ramp that tunes the local oscillator at the
rear-panel sweep output connector, J8. Connector J8 is
labeled LO SWP|FAV OUTPUT, (or LO
SWP|0.5V/GHz on older spectrum analyzers). Pressing
PRESET does not change J8 output of 0 → 10V.
Front-panel key access:
AUX CTRL
.5 V/GHz(FAV) For 8560E/EC, Agilent 8561E/EC or Agilent
8563E/EC only. Specifies a 0.5 volts per GHz voltage
output at the rear-panel connector J8.
