Table 27: IEEE-488 Device Compliance
Buffer Length
The buffer length is fixed at 256 characters.
Address
Every device on the IEEE-488 bus must have an address assigned to it. To set the address of 670
instrument, scroll to the IEEE-488 configuration screen, under the [
SETUP
] key menu. The
address entry ranges from 1 to 30. The 670 instrument is initially configured with the address set
to 8.
