In "Acquisition > Gated", the value of the parameter "Sweep Time/Duration" relates to
the effective time during that the signal is measured; the duration is determined by the
corresponding marker/markers signal (high values) and not to as an absolute duration/
sweep time.
Example:
A measurement with the following settings:
●
"Acquisition > Gated"
●
Duty cycle of the marker signal used as gate source = 1%
●
"Duration/Sweep Time = 1 s"
This measurement lasts effectively 100 s.
Remote command:
[:SOURce]:BB:MEASurement:POWer:DURation on page 1111
Level/PEP
Indicates the measured power level and peak power (PEP) retrieved according to the
selected acquisition method and at the selected acquisition point.
The power units depend on the selected output measurement point:
●
Measurements at the digital output interfaces (for example [BBMM1]) are represen-
ted in dBFs, as relative to full scale of 0.5 V
●
Measurements at the analog interfaces [I/Q ] in mV respectively
●
All other measurement results are represented in dBm.
Possible internal gains and attenuations are compensated.

[:SOURce]:BB:MEASurement:POWer:RMS? on page 1110
Run Mode
Determines whether the measurements are performed continuously with the selected
"Sweep Time" ("Auto") or are executed once ("Single").
"Auto"
This mode is suitable for measurements with short "Sweep Time" and
if several measurements are running simultaneously.
The measurement results are retrieved and updated continuously.
"Single"
This mode is suitable for measurements with longer measurement
time ("Duration").

Power Levels", on page 630.

Add, Change, Remove, Start, Abort
Standard function for measurements handling, like enabling a new measurement,
changing an existing one or starting/stopping current measurement. You can configure
and enable up to 8 measurements simultaneously, each with up to 32 submeasure-
ments.
