3. Connect any additional connectors from other instruments, as required for your application.
4. Ensure the other end of the cable is properly connected to the controller.
Set the GPIB address
The GPIB address value is set to 18 at the factory. You can set the address to any address between
0 and 30 if it is unique in the system. This address cannot conflict with an address that is assigned to
another instrument or to the GPIB controller.
GPIB controllers are usually set to 0 or 21. To be safe, do not configure any instrument to have an
address of 0 or 21. To change the controller address, see the documentation for the controller.
The address is saved in nonvolatile memory, so it does not change when a reset is done or when the
power is turned off and then turned on again.
From the front panel:
1. Press the MENU key.
2. Under System, select Communication. The SYSTEM COMMUNICATION window opens.
3. Select the GPIB tab.
4. Next to Address, select the number. The Set GPIB Address dialog box is displayed.
5. Enter the address.
6. Select OK.
If you are using a Model 2450 with no front panel, you can set the GPIB address with the SCPI
command :SYSTem:GPIB:ADDRess (on page 6-104) or the TSP command gpib.address (on page
8-65).
