provides a arbitrary frequency list mode. This
list is defined and modified using the edit list menu and the
edit
menu. Up to 30 frequency subsweeps (called
“segments”) of several different types can be specified, for
a maximum total of 1632 points One list is common to both
channels. Once a frequency list has been defined and a
measurement calibration performed on the full frequency list,
one or all of the frequency segments can be measured and
displayed without loss of calibration.
provides a tabular listing of all the measured data points and
their current values, together with limit information if it is
switched on. Thirty lines of data are listed on each page,
and the number of pages is determined by the number of
measurement points specified in the stimulus menu.

measures the line or match standard for PORT 2.
the standard type as a load (termination). Loads
are assigned a terminal impedance equal to the system
characteristic impedance ZO, but delay and loss offsets may still
be added. If the load impedance is not ZO, use the arbitrary
impedance standard
initiates measurement of a calibration standard load without
offset.

presents the load sequence from disk menu. Select the desired
sequence and the analyzer will load it from disk.
This key is used to return the analyzer to local (front panel)
operation from remote (computer controlled) operation. This
key will also abort a test sequence or hardcopy print/plot. In
this local mode, with a controller still connected on HP-IB, the
analyzer can be operated manually (locally) from the front
panel. This is the only front panel key that is not disabled
when the analyzer is remotely controlled over HP-IB by a
computer. The exception to this is when
lockout is in
effect: this is a remote command that disables the key,
making it difficult to interfere with the analyzer while it is
under computer control.
(Option 089 only) allows you to enter the frequency of the
external LO source.
activates a logarithmic frequency sweep mode. The source is
stepped in logarithmic increments and the data is displayed on
a logarithmic graticule. This is slower than a continuous sweep
with the same number of points, and the entered sweep time
may therefore be changed automatically. For frequency spans
of less than two octaves, the sweep type automatically reverts
to linear sweep.
