REFERENCE
PLANE
None
AUTO Automatically sets the reference delay so 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
XXX.XXXX mm
Electrically repositions the measurement reference plane, as
displayed on the active channel, 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 the test set’s Port 1 connector and the
device-under-test (DUT).
RDD; RDD?
TIME
XXX.XXXX ms
Electrically repositions the measurement reference plane by
a distance value that corresponds to the time in
milliseconds.
RDT; RDT?
SET DIELECTRIC
XXX
Displays menu RD2, which lets you enter a value for the
dielectric constant of your transmission line.
DIE
CONSTANT OFFSET Lets the user apply a constant offset vector to the channel
data. A constant magnitude and phase can be applied to the
data just after the reference plane is applied. The constant
offset is independent of frequency and media dispersion.
MAGNITUDE
+XXX.XXX dB
The magnitude is entered in dB and the phase in degrees.
These values are combined into a vector where the magnitude
is converted from Log to Linear . The channel dat a is then
vector multiplied by this vector.
