allows you to set different power levels at each port.
makes power level the active function and sets the RF
output power level of the analyzer’s internal source. The
analyzer will detect an input power overload at any of the
three receiver inputs, and automatically reduce the output
power of the source to -85 This is indicated with the
message “OVERLOAD ON INPUT (R, A, B).” In addition,
the annotation appears at the left side of the display.
When this occurs, set the power to a lower level, and toggle
OFF . If power meter cal is on, cal power is
the active entry.

brings up the segment modify menu and segment edit (power
loss) menu explained in the following pages. This is
intended for use when the power output is being sampled
by a directional coupler or power splitter. In the case of the
directional coupler, enter the power loss caused by the coupled
arm. Refer to Power Loss Feature on a previous page.
This feature may be used to compensate for attenuation
non-linearities in either a directional coupler or a power splitter.
Up to 12 segments may be entered, each with a different
frequency and power loss value.

turns on a power sweep mode that is used to characterize
power-sensitive circuits. In this mode, power is swept at a
single frequency, from a start power value to a stop power
value, selected using the and keys and the entry
block. This feature is convenient for such measurements as
gain compression or AGC (automatic gain control) slope. lb
set the frequency of the power sweep, use
in the
stimulus menu. Refer to the User’s Guide for an example of a
gain compression measurement.
Note that power range switching is not allowed in power sweep
mode.
In power sweep, the entered sweep time may be automatically
changed if it is less than the minimum required for the current
configuration (number of points, IF bandwidth, averaging, etc).
