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 <= 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
aid in remote operation and are negligible for front panel use. See "Using the
Electronic Attenuator: Pros and Cons" on page 801 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
Mechanical Attenuator Transition Rules
When the Electronic Attenuator is enabled, the Mechanical Attenuator transitions to
a state that has no Auto function. Below are the rules for transitioning the
Mechanical Attenuator. Note that the information below only applies to the Dual-
Attenuator configurations, and only when the Electronic Attenuator is installed:
When the Electronic Attenuation is enabled from a disabled state:
–
The Mechanical Attenuator is initialized to 10dB (this is its optimal performance
setting). You can then set it as desired with SCPI, numeric keypad, step keys, or
