METER:
' This section contains the procedure for reading the power meter. It is dependent on the
' particular meter you are using; therefore, the appropriate terminating characters have to
' be set. The main program expects the power to be returned in the variable POWER.
RETURN
SCPI Command Set
The GPIB interface of the attenuator conforms to the ANSI/IEEE standards 488.1-1987 and
488.2-1987. The RS232 interface conforms to ANSI/IEEE standard 488.2-1987 where
applicable.
The common commands are defined in ANSI/IEEE 488.2. All other commands conform to the
SCPI command language, version 1995.0.
