Attenuation

This menu 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 Configuration:" on page
See "Single Attenuator Configuration:" on page 353
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.

The maximum Ref Level is typically:
+30 dBm + RL Offset – External Gain (for MXA and PXA)
+23 dBm + RL Offset – External Gain (for EXA and CXA)
This maximum value is determined by the maximum power that can be safely
applied to the input circuitry. The actual maximum value at any given time
may be even less than this, depending on other values including Mech Atten,
Int Preamp Gain, Swept IF Gain, FFT IF Gain, Max Mixer Level, and the total
attenuation currently available.
