This command sets the power range extension attenuator. This command will also turn
off automatic attenuation setting. Refer to

[SOURce]:POWer:ATTenuation:AUTO OFF

for

details. Attenuator input RF power shall be -30…+10 dBm, e.g. using a
[SOURce]:POWer:ATTenuation value of 50 dB, the output RF power range is -80…-40
dBm.

(Devices with option PE only)
This command turns the power range extension on or off. Turning it off allows fast power
sweeps for devices featuring an extended output power range.

:ATTenuation:LIST?
[SOURce]:POWer:ATTenuation:LIST?
(Devices with option PE only)
This query returns a comma-separated list of available attenuation settings. These can be
set using the
