Preset 0dB
State Saved Saved in instrument state
Min 0dB
Max Dual-Attenuator configuration: 24dB
Single-Attenuator configuration: the total of ATT and EATT cannot exceed 50dB. So, if the EATT is set
to 24dB first, the main attenuation cannot be greater than 26dB and will be reduced accordingly; if
the main attenuator is set to 40dB first, EATT cannot be greater than 10dB

Example
:POW:EATT:STAT ON
:POW:EATT:STAT?
Preset OFF (Disabled) for Swept SA measurement
ON (Enabled) for all other measurements that support the electronic attenuator
NOTE
The maximum Center Frequency for Low Band can change based on the
selected IFBW for measurements that support IFBW (for example, Waveform
measurement across all Modes that support it). In certain models (such as
N9042B & N9032B), IFBW values <= 40MHz have a maximum Low Band
frequency of 3.6GHz, while 40MHz < IFBW <= 1GHz have a maximum of
3.3GHz, and 1GHz < IFBW <= 1.5GHz have a maximum of 3.5GHz. This
frequency is reflected in the disabled message displayed for Electrical
Attenuator. For N9032B and N9042B IFBW values > 1.5GHz do not support a
Center Frequency that can reach the Low Band maximum frequency. In these
cases, the Electrical Attenuator will remain disabled no matter the Center
Frequency.
More Information
The electronic attenuator offers finer steps than the mechanical attenuator, has no
acoustical noise, is faster, and is less subject to wear. These advantages primarily
aid in remote operation and are negligible for front panel use. See "Using the
Electronic Attenuator: Pros and Cons" on page 212 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 "Attenuator
Configurations and Auto/Man" on page 1641
