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 below -65
This is indicated with the
message “OVERLOAD ON INPUT (R, A, B).” In addition,

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

block. This feature is convenient for such measurements as
gain compression or AGC (automatic gain control) slope.

changed if it is less than the minimum required for the current
configuration (number of points, IF bandwidth, averaging, etc).
