Couplings When Auto Scaling is ON, and the Restart front-panel key is pressed, this function automatically sets
the scale per division to 10dB and determines the reference values based on the measurement results
When you change a value of "Scale/Div" on page 942, "Ref Value" on page 942, or "Scale Range" on
page 1612, Auto Scaling automatically changes to OFF

3.6.3.2 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 "Dual-Attenuator Configurations" on page 946
–
See "Single-Attenuator Configuration" on page 946
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.
