:NAMPs|NTACs:FVC:MESS <string>
:NAMPs|NTACs:FVC:MESS?
:NAMPs|NTACs:FVC:MESS?
These commands set/query the seven hexadecimal characters (28 bits)
of the FVC message. These 7 characters are combined with 12 parity
bits calculated by the encoder to output a 40-character data stream.
This data is output when the AFG2:NAMP:FVC:SEND ‘Message’
command is sent.
