Addressing

Set the instrument address by using the front panel controls on the

oscilloscope after the GPIB interface has been installed on the rear panel of

the oscilloscope.

1 Press

Print/Utility , then press the I/O Menu softkey.

2 Press the Inst Addr softkey to select the instrument address. Increment

the address by successively pressing the Inst Addr softkey. The address

can also be incremented or decremented by turning the knob closest to

the

Cursors key.

Each device on the GPIB resides at a particular address, ranging from 0 to

30.

The active controller specifies which devices talk and which listen.

An instrument may be talk addressed, listen addressed, or unaddressed by

the controller.

If the controller addresses the instrument to talk, the instrument remains

configured to talk until it receives an interface clear message (IFC), another

instrument’s talk address (OTA), its own listen address (MLA), or a universal

untalk command (UNT).

If the controller addresses the instrument to listen, the instrument remains

configured to listen until it receives an interface clear message (IFC), its own

talk address (MTA), or a universal unlisten command (UNL).
