3.8 SEM Measurement
If you Cancel, you will be prompted again the next time you turn NFE on. If you
postpone, you will be prompted again after a week passes and you then turn NFE
on.
Enable Wideband IF for FFT
When OFF, the maximum FFT BW is limited to 40 MHz. When ON, FFT with more
wideband IF is supported depending on the instrument. For example, the max FFT
BW is 510 MHz with option B5X. When ON for R10/R20/R40, the max FFT BW is
1GHz.
When this parameter is on and the following conditions are met, the measurement is
performed with a single I/Q acquisition.
–
Stop Freq of the outermost Offset range is within the available IQ acquisition BW
–
Same RBW, VBW, Detector Type settings across all Offset ranges and Carrier
–
Sweep Type = FFT and Sweep Time = Auto across all Offset ranges and Carrier
Remote Command
[:SENSe]:SEMask:WBFFt:ENABle ON | OFF | 1 | 0

Example
:SEM:WBFF:ENAB 1
:SEM:WBFF:ENAB?
Dependencies The maximum FFT BW depends on the µW preselector and the current frequency. In hi-band, the µW
preselector must be disabled to apply the FFT with wideband IF. Otherwise, the maximum FFT BW is
limited to 40MHz

3.8.18.6 Global
The controls in this menu apply to all Modes in the instrument.
Some controls (for example, "Global Center Freq" on page 1717) allow you to switch
certain Meas Global parameters to a Mode Global state. These switches apply to all
Modes that support global settings. For example, no matter what Mode you are in
when you set Global Center Freq to ON, it applies to all Modes that support Global
settings.
Other controls (for example, Extend Low Band) are actually set in this menu, but
apply to all Modes.
