3 Spectrum Analyzer Mode
3.4 Occupied BW Measurement
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 738
Remote Command
[:SENSe]:POWer[:RF]:EATTenuation <rel_ampl>
[:SENSe]:POWer[:RF]:EATTenuation?
Example
:POW:EATT 10
:POW:EATT?
Notes Electronic Attenuation’s specification is defined only when Mech Atten is 6dB
Dependencies Only appears in Dual-Attenuator models with an Electronic Attenuator installed and licensed. Does
not appear in models with the Single-Attenuator configuration, because 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. The “soft” attenuation is treated as an addition to the “main” attenuation value set by the
Attenuation control or :POW:ATT, and affects the total attenuation displayed on the Attenuation
