REFERENCE
PLANE PER
PORT
PORT X Select the port number. RPPORTNUM;
RPPORTNUM?
AUTO Changes the S-parameter being measured on the
active channel to the reflection S-parameter that
corresponds to the port number. Automatically sets
the reference delay such that the cumulative phase
shift is zero. This selection unwinds the phase in a
Smith chart display or reduces the phase revolutions
in a rectilinear display to less than one.
RDA
DISTANCE
XX.XXX mm
Electrically repositions the measurement reference
plane in all measurements as specified in “PORT X”
(above) by a distance value entered in millimeters.
This selection lets you compensate for the phase
reversals inherent in a length of transmission line
connected between.
RDD
TIME
XX.XXX ps
Electrically repositions the measurement reference
plane by a distance value that corresponds to the
time in picoseconds.
RDT
SET DIELECTRIC
XXXXX
Changes the soft-key display to the SET
DIELECTRIC menu.

Sets all the groups to BALANCED DIFFERENTIAL
S-parameters.

REFERENCE VALUE
XXX.XXX fS
Sets the value at the reference line for the active
channel amplitude measurement on the displayed
graph.
OFF; OFF2; OFF?;

REFERENCE LINE X Sets the reference line for the active channel
amplitude measurement. This is the line about which
the amplitude expands with different resolution
values.

PERCENT OF SWEEP
Sets the percent of frequency span over which group
delay is calculated.
