Example For example, if the instrument address is 4 and the interface select code is 7,
the instruction will cause an action in the instrument at device address 704.
DEVICE ADDRESS = (Interface Sel ect Code) × 100 + (Instr ument
Address)
Local, Remote, and Local Lockout
The local, remote, and remote with local lockout modes may be used for
various degrees of front-panel control while a program is running. The logic
analyzer will accept and execute bus commands while in local mode, and the
front panel will also be entirely active. If the Agilent 1670G-series logic
analyzer is in remote mode, the logic analyzer will go from remote to local
with any front panel activity. In remote with local lockout mode, all controls
(except the power switch) are entirely locked out. Local control can only be
restored by the controller.
CAUTION Cycling the power will restore local control, but this will also reset certain
GPIB states. It also resets the logic analyzer to the power-on defaults and
purges any acquired data in the acquisition memory.
The instrument is placed in remote mode by setting the REN (Remote
Enable) bus control line true, and then addressing the instrument to listen.
The instrument can be placed in local lockout mode by sending the local
lockout (LLO) command (see :LOCKout in chapter 9, "Instrument
Commands"). The instrument can be returned to local mode by either
setting the REN line false, or sending the instrument the go to local (GTL)
command.
