Attenuator Configurations and Auto/Man
As described under "Attenuation" on page 1954, there are two distinct attenuator
configurations available in the X-Series, the Single Attenuator and Dual-Attenuator
configurations.
In Dual-Attenuator configurations, we have mechanical attenuation and electronic
attenuation, and current total attenuation is the sum of electronic + mechanical
attenuation.
In Single-Attenuator configurations, we refer to the attenuation set using "Mech
Atten" on page 1253 (or :POW:ATT) as the “main” attenuation; and the attenuation
that is set by :POW:EATT as the “soft” attenuation (:POW:EATT is honored even in
the Single-Attenuator configuration, for compatibility purposes). Then current total
attenuation is the sum of main + soft attenuation.
See "Elec Atten" on page 1960 for more about “soft” attenuation.
NOTE
In some measurements, the Mech Atten control has an Auto/Man function. In
these measurements, an Auto/Man switch is shown on the Mech Atten control:
Note that in configurations that include an Electronic Attenuator, this switch is
only shown when the Electronic Attenuator is disabled.
In other measurements, Mech Atten has no Auto/Man function. In these
measurements, no switch is shown on the Mech Atten control:
