the Single-Attenuator configuration, for compatibility purposes). Then current total

attenuation is the sum of main + soft attenuation.

See "Elec Atten" on page 1769 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:

Mech Atten also appears with no switch, as above, in configurations that include

an Electronic Attenuator but when the Electronic Attenuator is enabled.

Elec Atten

Controls the Electronic Attenuator in Dual-Attenuator configurations. Does not

appear in Single-Attenuator configurations, because the control of both the

mechanical and electronic stages of the Single-Attenuator is integrated into the

single Atten control.

This control includes an Enable/Disable toggle switch; it is only possible to enter a

value for the Electronic Attenuator when this switch is in the Enable position.

For more details of the Electronic Attenuator, see "More Information" on page 429
