triggers a user-specified number of sweeps, and returns to
the hold mode. This function can be used to override the
test set hold mode (indicated by the notation “tsH” at the
left of the screen). In this mode, the electro-mechanical
transfer switch (Option 007) and attenuator are not
protected against unwanted continuous switching. This
occurs in a full two-port calibration, in a measurement of
two different parameters that require power out from both
ports, or when the channels are uncoupled and a different
power level is set for each channel.
If averaging is on, the number of groups should be at least
equal to the averaging factor selected to allow
measurement of a fully averagedtrace. Entering a number
of groups resets the averaging counter to 1.
is used to select the number of data points per sweep to be
measured and displayed. Using fewer points allows a
faster sweep time but the displayed trace shows less
horizontal detail. Using more points gives greater data
density and improved trace resolution, but slows the
sweep and requires more memory for error correction or
saving instrument states.
The possible values that can be entered for number of
points are 3, 11, 26, 51, 101, 201, 401,801, and 1601. The
number of points can be different for the two channels if
the stimulus values are uncoupled.
In list frequency sweep, the number of points displayed is
the total number of frequency points for the defined list
(see “Sweep Types” in the “Operating Concepts” chapter of
the user’s guide).
determines the number of measurement/correction
iterations performed on each point in a power meter
calibration. This feature helps eliminate residual power
errors after the initial correction. The amount of residual
error is directly proportional to the magnitude of the
initial correction. The user should initially set the source
power so that it is approximately correct at the device
under test. If power uncertainty at the device under test is
expected to be greater than a few dB, it is recommended
that the number of readings be greater than 1.
selects the calibration standard load as being offset.
is used to specify the one-way electrical delay from the
measurement (reference) plane to the standard, in seconds
(s). (In a transmission standard, offset delay is the delay
from plane to plane.) Delay can be calculated from the
precise physical length of the offset, the permittivity
