Checking for
Installed Drawers
The MOD:LIST? command may be used to query the 1257 for the
drawer type present in the system.
[ROUTe]
:MODule
:LIST?
[module
address]
As an example, if a 1257 contains a 1260-601A drawer and if the
following command was executed:
MOD:LIST?
the reply would be:
1 : 1260-601A SPECIAL MATRIX
The command can also be queried with the drawer number:
MOD:LIST?
(@1)
Where the reply would be the same:
1 : 1260-601A SPECIAL MATRIX
This command is NOT defined in the SCPI standard. This
command follows the syntax rules of SCPI to implement this
functionality.
System
Commands
The 1257 instrument supports several system commands. These
commands generally access errors, SCPI standard information, as
well as user-interface issues. Additionally, the 1257 uses a special
command to update non-volatile memory.
Reading Error
Messages
Whenever an error is encountered by the 1257, it will perform two
actions:
1. One of the bits of the
Standard Event Status Register
will be
set. This register may be read using the *ESR? query
2. An error message will be added to the error message queue.
The error message queue may be read using the
SYSTEM:ERROR? query (or SYST:ERR?).
Consult Appendix B for a list of error messages and more detailed
explanations.
