wideband signals with occupied bandwidths up to 2GHz. This increases the risk
of images failing to be rejected, but improves the measurement speed

:POW:SWPR:BW NARR
Dependencies Only appears in N9041B and N9042B+V3050A. Only appears in measurements that use the Swept
method
Grayed-out when "Software Preselection" on page 1992 is OFF. The grayout message is “Unavailable

For N9042B+V3050A, the parameter is SCPI-only, and always set to NARRow when Software
Preselection is enabled

High Freq Prefilter
Lets you set the state of Prefilter for center frequencies above 1310MHz.
In VXT Models M9410A/11A and M9410E/11E in bypass frequency range
(1310MHz~5GHz), the Receiver RF path has a bank of filters that come after the RF
Attenuator in the signal path. Since this bank of filters precedes the mixer they are
known as the “Prefilter” bank. Their purpose is to eliminate unwanted in-band
mixing products by filtering out all but the desired frequencies before the signals get
to the mixer. There are 13 prefilter bands to cover the frequencies between 9kHz
and 6000MHz. The Prefilter provides the necessary rejection of the unwanted
signal.
