and are negligible for front panel use. See
"Using the Electronic Attenuator: Pros and Cons" on
for a detailed discussion of the pros and cons of using the electronic attenuator.
For the single attenuator configuration, for SCPI backwards compatibility, the “soft” attenuation
feature replaces the dual attenuator configuration’s electronic attenuator. All the same couplings
and limitations apply. See

This key only appears in Dual Attenuator models with an Electronic Attenuator installed. It does
not appear in models with the Single Attenuator configuration, as in the single attenuator
configuration there is no “electronic attenuator” there is only a single integrated attenuator
(which has both a mechanical and electronic stage). However, in the single attenuator
configuration, EATT SCPI commands are accepted for compatibility with other X-series
instruments and set a “soft” attenuation as described in
"Attenuator Configurations and
The electronic attenuator (and the “soft” attenuation function provided in single attenuator
configurations) is unavailable above 3.6 GHz. Therefore, if the Stop Frequency of the analyzer is
> 3.6 GHz then the Enable Elec Atten key will be OFF and grayed out.
If the Internal Preamp is on, meaning it is set to Low Band or Full, the electronic attenuator (and
the “soft” attenuation function provided in single attenuator configurations) is unavailable. In
this case the Enable Elec Atten key will be OFF and grayed out.
If either of the above is true, if the SCPI command is sent, an error indicating that the electronic
attenuator is unavailable will be sent.
If the electronic/soft Attenuator is enabled, then the Stop Freq of the analyzer is limited to
3.6 GHz and the Internal Preamp is unavailable.
The SCPI-only “soft” electronic attenuation for the single-attenuator configuration is not
available in all measurements; in particular, it is not available in the Swept SA measurement.
Couplings
Enabling and disabling the Electronic Attenuator affects the setting of the Mechanical
Attenuator (in dual attenuator configurations). This is described in more detail below this table.
