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 and in "Mechanical Attenuator
Transition Rules" on page 1962
Preset 0dB
State Saved Saved in instrument state
Min 0dB
Max Dual-Attenuator configuration: 24dB
Single-Attenuator configuration: the total of ATT and EATT cannot exceed 50dB. So, if the EATT is set
to 24dB first, the main attenuation cannot be greater than 26dB and will be reduced accordingly; if
the main attenuator is set to 40dB first, EATT cannot be greater than 10dB

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 <= 40MHz have a maximum Low Band
frequency of 3.6GHz, while 40MHz < IFBW <= 1GHz have a maximum of
3.3GHz, and 1GHz < IFBW <= 1.5GHz have a maximum of 3.5GHz. This
frequency is reflected in the disabled message displayed for Electrical
Attenuator. For N9032B and N9042B IFBW values > 1.5GHz 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
