ML24XXA NATIVE
COMMANDS
This section provides an alphabetical listing of the GPIB commands (mnemonics)
used to program the Model ML2430A Series Power Meter in ML24XXA (native)

or through the GPIB command EMUL (page 6-35).
All ML24XXA (native) GPIB commands that use parameters must
have a space
between the command header and the first parameter, and all subsequent pa

the same line, but must be separated by a semicolon (;).
The format for ML24XXA (native) GPIB commands is:

The end of the command text must be terminated with a line feed character (0Ah,
decimal 10) or a GPIB End of Transmission State (EOI), or both.
