General bus commands
General commands are commands that have the same general meaning, regardless of the
instrument (for example, DCL). The following table lists the general bus commands.
General bus commands
Command Effect on Model 2110
REN
Goes into remote operation when next addressed to listen. See REN (on page C-9) for
details.
IFC
Goes into talker and listener idle states. See IFC (on page C-9) for details.
LLO
LOCAL key locked out. See LLO (on page C-9) for details.
GTL
Cancel remote; restore Model 2110 front-panel operation. See GTL (on page C-9) for
details.
DCL
Returns the Model 2110 and all devices on the GPIB to known conditions. See DCL (on
page C-10) for details.
SDC
Returns the Model 2110 to known conditions. See SDC (on page C-10) for details.
GET
Initiates a trigger. See GET (on page C-10) for details.
SPE, SPD
Serial polls the Model 2110. See SPE, SPD (on page C-10) for details.
REN
The remote enable (REN) command is sent to the Model 2110 by the controller to set up the
instrument for remote operation. Generally, the instrument should be placed in the remote mode
before you attempt to program it over the bus. Setting REN true does not place the instrument in the
remote state. You must address the instrument to listen after setting REN true before it goes into
remote operation.
IFC
The interface clear (IFC) command is sent by the controller to place the Model 2110 in the talker idle
state and the listener idle state.
Transfer of command messages to the instrument and transfer of response messages from the
instrument are not interrupted by IFC. If transfer of a response message from the instrument was
suspended by IFC, transfer of the message will resume when the instrument is addressed to talk. If
transfer of a command message to the instrument was suspended by IFC, the rest of the message
can be sent when the instrument is addressed to listen.
LLO
When the instrument is in remote operation, all front-panel controls are disabled, except the LOCAL
key (and the POWER switch). The local lockout (LLO) command disables the LOCAL key.
GTL
Use the go to local (GTL) command to put a remote-mode instrument into local mode. Leaving the
remote state also restores operation of all front-panel controls.
