l-56 Getting Started Programming
Figure C-2 shows the swept signal generator rear-panel HP-IB
connector and suitable cables, and describes the procedures and
limitations for interconnecting instruments. Cable length restrictions,
also described in Figure C-2, must be observed.
Each instrument in an HP-IB network must have a unique address,
ranging in value from 00-30 (decimal). The default address for the
swept signal generator is 19, but this can be changed using the
My Adrs softkey or rear panel switch as described in the reference
chapter (Chapter 2) under the “8360 Adrs” entry (the examples in
this section use 19 as the address for the swept signal generator).
Other instruments use a variety of procedures for setting the address,
as described in their operating manuals, but typically either a rear
panel switch or a front panel code is used.
An HP-IB instrument is categorized as a “listener,” “talker,” or
“controller,” depending on its current function in the network.
Listener
A listener is a device capable of receiving data or commands from
other instruments. Any number of instruments in the HP-IB network
can be listeners simultaneously.
Talker
A talker is a device capable of transmitting data or commands to
other instruments. To avoid confusion, an HP-IB system allows only
one device at a time to be an active talker.
Controller
A controller is an instrument, typically a computer, capable of
managing the various HP-IB activities. Only one device at a time
can be an active controller.
The swept signal generator can be controlled entirely by a computer
(although the line POWER switch must be operated manually).
Several functions are possible only by computer (remote) control.
Computer programming procedures for the swept signal generator
involve selecting an HP-IB command statement, then adding
the specific swept signal generator (SCPI, Analyzer, or CIIL)
programming codes to that statement to achieve the desired
operating conditions. The programming codes can be categorized
into two groups: Those that mimic front panel keystrokes; and those
that are unique, and have no front panel equivalent.
