ATTenuation
ATTenuation can be used as both a query and as a command to set device
parameters. ATTenuation has three parameters: DB, DBR, and MIN. Use the
DB term to query or set attenuation in absolute terms relative to minimum
attenuation. To query or set attenuation values relative to the REFerence
value, use the DBR term. To set the attenuation to the minimum (0 dB), use
the MIN term.
NOTE
Attenuation can be changed even if the light shutter is closed.
