Remote Operation
Using GP-IB
Operating Distances
Up to 15 instruments can be connected on a local bus system, but it is important to ensure
that the maximum GP-IB cable length between instruments is less than 2 meters. In
addition the total cabling should not exceed 20 meters.
Some useful cable part numbers are listed in Table 1-1.
Instrument Mode at Power On
At power on the Agilent 71612 Series will wake up in the same mode as it was powered
down in. Normally, at power on, the Agilent 71612 Series is ready for either front panel
operation or remote operation.
CAUTION No GP-IB activity should take place within 20 seconds of system
power up, as this will effect the system power up routine and may result
in system hang up.
Address Configuration
When configuring a GP-IB based system it is essential that each device on the GP-IB has
a unique address. The device address can be in the range of 1 to 30. For a controller to
communicate with a device over the GP-IB it must send the commands to the appropriate
GP-IB device address.
Local and Remote Modes
The Agilent 71612 Series can be operated in one of two modes: local or remote.
In local operation, all the front controls are responsive and control the instrument.
In remote operation the softkeys which configure the system are inoperative, with
exception of the display softkeys, and the instrument is controlled by the GP-IB controller.
The front panel display reflects the remote programming commands received.
