Key Path
Pwr Avg (RMS) Sets the signal power level (the square of the magnitude) as the scale for
the filtering and averaging processes. This scale is sometimes called RMS because the
resulting voltage is proportional to the square root of the mean of the square of the voltage.

Key Path
Limit Mask 1 (upper) or Limit Mask 2 (Lower)
Limit Mask 1 (upper) access the upper limit mask keys.
Limit Mask 2 (Lower) access the lower limit mask keys.
You can define a limit mask that matches your maximum or minimum measurement
requirements. This mask can then be compared with the measured trace data to determine
pass/fail conditions.
Limit Trace
Selects the trace to which the currently selected limit mask (1 or 2) will be applied. The limit masks
can be applied to separate traces. Only 2 traces are available in the Stimulus Response mode
(compared to 4 traces in the Spectrum Analyzer Mode).

The Limit Mask 1 (Upper) menu link key accesses the keys to
configure the upper limit mask for the Center, 1
segments (dependent on selected segment).
The Limit Mask 2 (Lower) menu link key accesses the keys to
configure the lower limit mask for the Center, 1
segments (dependent on selected segment).
