Gpib Compatibility; Remote Mode; Local Mode - Agilent Technologies 11713A Operating And Service Manual

Remote Operation
The driver can be operated remotely through the General Purpose
Interface Bus (GPIB).

GPIB Compatibility

Remote-only functions and all front panel functions (except the LINE
switch) are programmable through the GPIB. The operator's interface
check in Chapter 4, "Verification" provides a test of the GPIB to verify
that the driver can function with each of the applicable bus messages.
Table 6-1 summarizes the driver's GPIB capabilities in terms of the
twelve bus messages.

Remote Mode

The driver accepts commands from the bus in the remote mode. In
remote, its front panel controls are disabled (except for the LINE switch
and the LOCAL pushbutton). The LOCAL pushbutton can be disabled
by a local lockout command. The driver can be addressed to listen and
when addressed to listen, the driver will respond to the following
messages: Data, Remote, Local Lockout, and Clear Lockout/Set Local.
Local-to-Remote Changes
The driver switches to remote operation upon receipt of the Remote
message. The Remote message has two parts:
• Remote enable bus control line (REN) set true
• Device listen address (MLA) received once (while REN is true)
The driver's outputs and all control settings remain unchanged with
the Local-to-Remote transition. The REMOTE LED is ON when the
driver is in the remote state.

Local Mode

In local, the driver's front-panel controls are fully operational and the
instrument will respond to the Remote message. Whether addressed or
not, it will also respond to the Local Lockout and Clear Lockout/Set
Local messages.
Remote-to-Local Changes
The driver returns to local control upon receipt of the Clear Lockout/Set
Local message (REN). If the driver is not in Local Lockout, it switches
to local from remote when the front panel LOCAL key is pressed. With
the remote-to-local transition, the driver's outputs remain unchanged.
