1-8 GPIB Interconnection and Setup
GPIB Interconnection
The only interconnection required for GPIB operation is between the signal generator and the controller.
This interconnection is via a standard GPIB cable. The Anritsu part number for such a cable is 2100-1, -2, or -4
(1, 2, or 4 meters in length).
GPIB Cable Length Restrictions
The GPIB can accommodate up to 15 instruments at any one time. To achieve design performance on the bus,
proper timing and voltage level relationships must be maintained. If either the cable length between separate
instruments or the cumulative cable length between all instruments is too long, the data and control lines
cannot be driven properly and the system may fail to perform. Cable length restrictions are as follows:
• No more than 15 instruments may be installed on the bus.
• Total cumulative cable length (in meters) may not exceed two times the number of bus instruments or
20 meters—whichever is less.
Setting the GPIB Address
The default GPIB address is five. If a different GPIB address is desired, it can be set from the front panel using
the Configure GPIB menu.
To change the GPIB address:
1. Press the front panel main menu key labeled System.
The System menu is displayed.
2. Press the Config soft key.
The System Configuration menu (Figure 1-3) is displayed.
Note
For low EMI applications, the GPIB cable should be a fully shielded type with well-grounded
metal-shell connectors.
