Defines the tuning coefficients of the proportional-integral (PI) controller the analyzer
uses as a feedback controller for ALC; see
By default the parameters are selected by the analyzer firmware ("Coefficients" =
"Auto"). With automatic selection of the
, this option is the only
one. If "ALC Path IF Bandwidth" is set manually, it is also possible to vary the propor-
tional gain "Kr", the integration time "Ti", and the "Control Time" manually.
The latter specifies the maximum duration of the control loop phase, per measurement
point. With "Auto Settling" enabled, the firmware exits the control loop when the con-
vergence criteria are met, and does not wait until the "Control Time" has elapsed.

Time Domain X-Axis tab
If the active trace is a time domain trace, these settings define its stimulus axis.
Time domain analysis requires option R&S
ZNA-K2. If this option is not installed, the
"Time Domain X-Axis" tab is hidden.
