The Current Setting interrogate command CST tells the
HP
81 12A
to send a response that contains all necessary commands to set the
device to its present state. The response message, called
(
ASCII
)
learn string, can be retransmitted as a program message without
alteration.
The learn string may be altered in the computer before
retransmitting it. Since the learn string is made up of the several
independent commands, it is possible to send parts of the learn string
(
complete commands
)
to the instrument.
The description of the example program LRN _DEMO in Chapter
7
Programming Examples
contains more details about the usage of the
CST command. Also refer to the example program INTERROG.
