Couplings When Auto Scaling is ON, and the Restart front-panel key is pressed, this function automatically sets
the scale per division to 10dB and determines the reference values based on the measurement results
When you set the value of either Scale/Div, Ref Value, or Scale Range manually, Auto Scaling automat-
ically changes to OFF

3.9.13.2 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.

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.
