Analyzer Functions
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.
toggles between or . These power meters
are GPIB compatible with the analyzer. The model
number in the softkey label must match the power meter
to be used.
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. To 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.).

is used to select a preset condition defined by the user.
This is done by saving a state in a register under
and naming the register UPRESET. When
is underlined, the key will
bring up the state of the UPRESET register.
selects a menu to set the preset states of some items, such
as calibration interpolation and step sweep mode.
steps backward through a tabular list of data
page-by-page.
steps back to the previous range menus.
when displaying list values, prints the entire list in color.
When displaying operating parameters, prints all but the
last page in color. The data is sent to the printer as ASCII
text rather than as raster graphics, which causes the
printout to be faster.
