6.2.5 GPIB Address
This interface is optional on the 7630. Each device on the GPIB (IEEE-488) interface must
have a unique address. You can set the address of the 7630 to any value between 0 and 30.
The address is set to 9 when the instrument is shipped from the factory. The address can only
be set from the front panel. The address is stored in non-volatile memory and does not
change when the power has been off or after a remote reset.
