UNIT ATTENUATION 2 WITHOUT LOG = AN2
The SET command requires a three-digit parameter representing the attenuation in dB. The three-character string “INC”
or “DEC” can be used in place of the attenuation parameter to increment or decrement the attenuator by 0.2 dB. This
event is logged in the unit event log.
