3.3.3.2 Attenuation
Controls the attenuator functions and interactions between the attenuation system
components.
There are two attenuator configurations in the X-Series. One is a Dual-Attenuator
configuration consisting of a mechanical attenuator and an optional electronic
attenuator. The other configuration uses a single attenuator with combined
mechanical and electronic sections that controls all the attenuation functions.
Different models in the X-Series come with different configurations.

See "Single-Attenuator Configuration" on page 330
Most attenuation settings are the same for all measurements – they do not change
as you change measurements. Settings like these are called “Meas Global” and are
unaffected by Meas Preset.
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
