Use this feature to add electrical delay (in seconds) to extend
the reference plane at input A to the end of the cable. This is
used for any input measurements including S-parameters,
adds electrical delay to the input B reference plane for any B
input measurements including S-parameters.
extends the reference plane for measurements of &I, S21, and
extends the reference plane for measurements of !& S12, and
toggles the reference plane extension mode. When this function
is on, all extensions defined above are enabled; when off, none
of the extensions are enabled.

defines the load in a calibration kit as a fixed (not sliding) load.
is used only with a polar or Smith format. It changes the
auxiliary response value of the fixed marker. This is the second
part of a complex data pair, and applies to a magnitude/phase
marker, a real/imaginary marker, an R+ jX marker, or a G+ jB
marker. Fixed marker auxihary response values are always
uncoupled in the two channels.
leads to the fixed marker menu, where the stimulus and
response values for a fixed reference marker can be set
arbitrarily.
changes the stimulus value of the fixed marker. Fixed marker
stimulus values can be different for the two channels if the
channel markers are uncoupled using the marker mode menu.
