Sweep and Trigger Reset
Resetting the sweep system resets the average/hold count k to 0. It also resets the
set point counter to 0. Resetting the trigger system resets the internal auto trig
timer to the value set by the Auto Trig control.
Averaging
The weighting factor used for averaging is k. This k is also the average/hold count
for how many valid sweeps (data acquisitions) have been done. This k is used for
comparisons with N, as those comparisons always needs to be based on valid
completed sweeps.
The displayed average/hold, K, shows the count for the sweep (data acquisition) in
progress. K = k + 1, with a limit of N. The displayed value K changes from its previous
value to 1 as soon as the trigger condition for the first data acquisition (sweep) is
met.
3.11.9.2 Sweep Config
Lets you configure the Sweep and Control functions of the instrument , such as
Sweep Rules.
Only appears in VXT.
IF Dithering
Lets you turn IF Dithering on or off. This is a technique used in unpreselected
instruments (such as Keysight’s modular instruments) to enhance the rejection of
images and internally-generated spurious signals.
