3 Spectrum Analyzer Mode
3.4 Occupied BW Measurement
Only available when the hardware set includes an input attenuator, which is
typically only the case for Keysight’s benchtop instruments. For example, this tab
does not appear in VXT models M9420A/10A/11A/15A/16A,
M9410E/11E/15E/16E, nor in UXM. In UXM, all Attenuation and Range settings are
disabled, as the expected input power level is handled by the Call Processing App
that drives the DUT power control.
Dependencies In measurements that support the I/Q inputs, unavailable when I/Q is the selected input. Replaced by
the Range tab in that case
Dual-Attenuator Configurations
Configuration 1: Mechanical attenuator + optional electronic attenuator
Configuration 2: Mechanical attenuator, no optional electronic attenuator
Note that Configuration2 is not strictly speaking a dual-section attenuator, since
there is no electronic section available. However, it behaves exactly like
Configuration 1 without the Electronic Attenuator Option EA3, therefore for the sake
of this document it is grouped into the “Dual-Attenuator” configuration.
Single-Attenuator Configuration
