[:SOURce[n]][:CHANnel[m]]:POWer:ATTenuation: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.
