General bus commands
General commands are those commands, such as DCL, that have the same gen-
eral meaning regardless of the instrument. Table 14-1 lists the general bus com-
mands.
Front panel GPIB operation
This section describes aspects of the front panel that are part of GPIB operation,
including messages, status indicators, and the LOCAL key.
Error and status messages
See Appendix B for a list of error and status messages associated with IEEE-488
programming. The instrument can be programmed to generate an SRQ, and com-
mand queries can be performed to check for specific error conditions.
GPIB status indicators
The REM (remote), TALK (talk), LSTN (listen), and SRQ (service request) annun-
ciators show the GPIB bus status. Each of these indicators is described below.
REM
This indicator shows when the instrument is in the remote state. When the instru-
ment is in remote, all front panel keys, except for the LOCAL key, are locked out.
