Remote command:
n.a.
In remote control, the trace is selected by the suffix of keyword
TRACe
.
Indication
(time measurement mode only)
Indicates the type of R&S NRP power sensor assigned to the selected trace. This field
is automatically updated if the sensor is connected or disconnected. Additionally, this
sensor is indicated on the trace button in the measurement diagram.
Remote command:
n.a.
State - Pulse Data Analysis
Enables pulse data analysis. The measurement is started with the "Start" button in the
main measurement diagram.

Voltage / Power Related - Pulse Data Analysis
Selects how the threshold parameters are calculated, either voltage related or power
related. The voltage-related parameters represent the normal case, as the usual repre-
sentation when defining the pulse parameters (rise/fall time, pulse width) is U(t). To
achieve a display with equivalent power-related values, the voltage-related threshold
values must be converted (squared) (see example in table below).

Distal - Pulse Data Analysis
Sets the upper reference level in terms of percentage of the overall pulse level (power
or voltage related). The distal power defines the end of the rising edge and the start of
the falling edge of the pulse.
