but invalid arguments
found)
AFR*(message OK,
but not permitted in
current mode) AFR? AFR=x
(same format as
command
arguments)
Attenuation ATT=xx.xx BDC
BUC
5 bytes,
numeric Command or Query.
Valid attenuation level, in dB, at 0.25dB step size as factory
default.
Example: ATT=08.25 ATT=(message OK)
ATT? (received OK,
but invalid arguments
found)
ATT*(message OK,
but not permitted in
