●
Switch off the RF power source for zeroing, but do not disconnect it from the power
sensor. This proceeding keeps the thermal equilibrium, and the zeroing process
also compensates the noise that superimposes the measured signal (e.g. from a
broadband amplifier).
Pulse Data
Accesses the dialog for configuring the settings for pulse data analysis.
See "Trace settings" on page 265.
Trigger..
Accesses the dialog for configuring the trigger settings.
See "Trigger settings" on page 272
Level Offset State- Power Analysis
Activates a level offset at the sensor input. Set the offset value in the entry field on the
right.
Remote command:
:SENSe<ch>[:POWer]:SWEep:FREQuency[:SENSor]:OFFSet:STATe
on page 504
:SENSe<ch>[:POWer]:SWEep:TIME[:SENSor]:OFFSet:STATe on page 507
:SENSe<ch>[:POWer]:SWEep:TIME[:SENSor]:OFFSet:STATe on page 507
Level Offset - Power Analysis
Sets the level offset at the sensor input. To consider the value, activate the offset.
Remote command:
:SENSe<ch>[:POWer]:SWEep:FREQuency[:SENSor]:OFFSet on page 504
:SENSe<ch>[:POWer]:SWEep:POWer[:SENSor]:OFFSet on page 506
:SENSe<ch>[:POWer]:SWEep:TIME[:SENSor]:OFFSet on page 507
Use S-Parameter - Power Analysis
Activates the use of the S-parameters correction data of the connected power sensor.
For sensors with attenuator, this checkbox is automatically checked.
Refer also to the manual of the connected R&S power sensor for a description on how
to use the S-parameters table.
Use Separate Frequency- Power Analysis
This setting is offered for measurements with DUTs that change the measurement fre-
quency (like modulators), thus changing the input frequency of the sensor.
The parameters vary depending on the measurement modes:
●
Power versus frequency measurement
Activates the use of a different frequency range other than the set signal generator
frequency range for the measurement. The separate minimum and maximum fre-
quency values are set below.
The x-scale of the diagram can be adjusted to the separate frequency range with
functions "Use as X Scale" and "Map to X Scale".
