[:SOURce[n]][:CHANnel[m]]:POWer:ATTenuation[l]:AUTO
[:SOURce[n]][:CHANnel[m]]:POWer:ATTenuation[l]:AUTO<wsp>OFF|ON|0|1
Selects Automatic or Manual Attenuation Mode.
In Automatic Attenuation Mode, you specify the output power.
In Manual Attenuation Mode, you must specify both the laser output power, and the attenu-
ation level.
OFF or 0:
ON or 1:
none

[:SOURce[n]][:CHANnel[m]]:POWer:ATTenuation[l]:DARK
[:SOURce[n]][:CHANnel[m]]:POWer:ATTenuation[l]:DARK<wsp>OFF|ON|0|1
Sets or unsets the attenuator to 'dark' position.
Dark position blocks all light from the laser. You can use this as an alternative to disabling
the laser, the advantage of doing this is that you avoid the laser rise time.
This command is available in Attenuation Mode Only.
