1.2 GP-IB Interface Functions
GP-IB Interface Functions
Listener Capability
• All of the information that you can set with the panel keys can be set through the GP-
IB interface except for turning ON/OFF the power and setting the communication
parameters.
• Receives commands from a controller requesting the output of setup parameters,
measured/computed data, waveform data, and other information.
• Also receives status report commands.
Talker Capability
• Outputs setup parameters, measured/computed data, waveform data, and other
information.
Note
Talk-only, listen-only, and controller functions are not available on this instrument.
Switching between Remote and Local Modes
When Switching from Local to Remote Mode
Receiving a REN (Remote Enable) message from the controller when the instrument is
in the local mode causes the instrument to switch to the remote mode.
• The REMOTE indicator is turned ON.
• All keys except the LOCAL key are disabled.
• Settings entered in local mode are retained even when this instrument switches to
remote mode.
When Switching from Remote to Local Mode
Pressing LOCAL key in remote mode puts the instrument in local mode. However, this
act is invalid if the instrument has been set to Local Lockout mode (see page 1-6) by the
controller.
• The REMOTE indicator is turned OFF.
• Key operations are enabled.
• Settings entered in remote mode are retained even when this instrument switches to
local mode.
Note
The GP-IB interface cannot be used simultaneously with other communication interfaces (RS-
232, USB, or Ethernet).
