"Linear"
●
Power versus frequency
In a linear sweep, the frequency is swept in equidistant steps over
the continuous frequency range. The x-axis is a linear frequency
axis.
●
Power versus power
The sweeps are performed at constant frequency but with vari-
able generator power that is swept in linear, equidistant steps
over a continuous range. The x-axis is a dB-linear power axis.
●
Power versus time
The sweeps are performed at constant frequency and stimulus
power. The measurement is repeated over a specified period of
time at constant time intervals.
"Logarithmic"
Power versus frequency
In a logarithmic sweep, the frequency is swept in equidistant steps on
a logarithmic scale. The x-axis is a logarithmic frequency axis.
Remote command:

:SENSe[:POWer]:SWEep:TIME:SPACing[:MODE]
Execution - Power Analysis
Selects single or continuous mode in power analysis.
The measurement is started in the diagram using the "Start" button. During measure-
ment, the "Start" button is replaced by a "Stop" button which can be used to abort the
measurement. The progress bar indicates the status of the measurement.
Note:
For time mode, an additional trigger is required (see
"Single"
Selects single measurement.
"Cont."
Selects continuous measurements.

:SENSe[:POWer]:SWEep:TIME:RMODe
All Trigger Events - Power Analysis
Ddetermines, whether the measurement data processing starts with a trigger event in
one of the sensors (Logical OR), or whether all channels have to be triggered (logical
AND). Each sensor evaluates a trigger event according to its setting independently.
This function supports the internal or external trigger modes with multi-channel time
measurements.
"Wired AND"
When all channels are triggered, the measurement starts.
"Wired OR"
The measurement starts when a trigger event occurs.
