Channel Bandwidth
Defines the channel bandwidth on which the total power density is based. The band-
width is positioned around the currently defined
To specify a different bandwidth for total power density calculation, or to shift the band-
width, define an
manually.
Remote command:
[SENSe:]NPRatio:CHANnel:BWIDth
Integration Bandwidth
Defines a bandwidth other than the channel bandwidth to be used for total power den-
sity calculation. Select the "Manual" option and define the bandwidth manually.
In auto mode, the integration bandwidth is the same as the channel bandwidth.
Notches are deducted from the results.
In manual mode, you can customize the integration bandwidth. The results include the
power levels measured within notches, however.
A "Frequency Offset" shifts the bandwidth away from the currently defined
.
Remote command:
[SENSe:]NPRatio:CHANnel:INTegration:BWIDth
[SENSe:]NPRatio:CHANnel:INTegration:AUTO
[SENSe:]NPRatio:CHANnel:INTegration:FREQuency:OFFSet
Number of Notches
Defines the number of notches for which results are determined. A maximum of 25
notches can be defined. Note that even if bandwidths for further notches are defined,
only the number specified here are actually calculated and displayed.
If
Generator Control State (FSW -> SMW)
is enabled in the generator settings, the
specified number of notches is sent to the generator on upload. An LED next to the
setting indicates whether the setting was adjusted on the connected instrument suc-
cessfully.
See
on page 221 for more information about how
notches are treated in the measurement.
Remote command:
[SENSe:]NPRatio:NOTCh<notch>:COUNt
CONFigure:GENerator:NPRatio:NOTCh<notch>:COUNt:CSTate?
Generator Notch Filter State
Activates or deactivates a notch filter on the signal generator.
