GPIB, the Generic Interface Bus, is the instrument-to-instrument
communication system between the sweeper and up to 14 other instruments.
Any instrument having GPIB capability can be interfaced to the sweeper,
including non-Agilent instruments that have \GPIB," \IEEE-488," \ANSI
MC1.1," or \IEC-625" capability (these are common generic terms for GPIB;
all are electrically equivalent although IEC-625 uses a unique connector).
This portion of the manual specically describes interfacing the sweeper to a
computer.
The rst part of this section provides general GPIB information. Later, the
Standard Commands for Programmable Instruments language (SCPI) is
introduced, and example programs are given.

GPIB General Information
Interconnecting Cables
The Installation Guide shows the sweeper rear-panel GPIB connector
and suitable cables, and describes the procedures and limitations for
interconnecting instruments. Cable length restrictions, also described in the
Installation Guide, must be observed to prevent transmission line propagation
delays that might disrupt GPIB timing cycles.
Instrument Addresses
Each instrument in an GPIB network must have a unique address
ranging in value from 0 to 30. The default address for the sweeper is 19, but
this can be changed using the

GPIB General Information
GPIB Instrument Nomenclature
An GPIB instrument is categorized as a \listener," \talker," or \controller,"
depending on its current function in the network.
A listener is a device capable of receiving data or commands from other
instruments. Any number of instruments in the GPIB network can be
listeners simultaneously.
A talker is a device capable of transmitting data or commands to other
instruments.To avoid confusion, an GPIB system allows only one device at a
time to be an active talker.
A controller is an instrument, typically a computer, capable of managing the
various GPIB activities. Only one device at a time can be an active controller
.
Programming the Sweeper
The sweeper 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 sweeper involve selecting an GPIB command statement, then adding the
specic sweeper (SCPI, Analyzer) 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.
In the programming explanations that follow, specic examples are included
that are written in a generic dialect of the B
selected because the majority of GPIB computers have B
capability. However, other languages can also be used.

GPIB Command Statements
Command statements form the nucleus of GPIB programming; they are
understood by all instruments in the network and, when combined with
the programming language codes, they provide all management and data
communication instructions for the system.
An explanation of the
However, some computers use a slightly dierent terminology, or support an
extended or enhanced version of these commands. Consider the following
explanations as a starting point, but for detailed information consult the
BASIC language reference manual, the I/O programming guide, and the GPIB
manual for the particular computer used.
Syntax drawings accompany each statement: All items enclosed by a circle or
oval are computer specic terms that must be entered exactly as described;
items enclosed in a rectangular box are names of parameters used in the
statement; and the arrows indicate a path that generates a valid combination
of statement elements.

GPIB General Information
Abort
Abort abruptly terminates all listener/talker activity on the interface bus,
and prepares all instruments to receive a new command from the controller.
Typically, this is an initialization command used to place the bus in a known
starting condition. The syntax is:
where the interface select code is the computer's GPIB I/O port, which is
typically port 7. Some BASIC examples:
10 ABORT 7
100 IF V>20 THEN ABORT 7

Remote
Remote causes an instrument to change from local control to remote control.
In remote control, the front panel keys are disabled (except for the
key and the POWER switch), and the REMOTE annunciator is lighted. The
syntax is:
where the device selector is the address of the instrument appended to the
GPIB port number. Typically, the GPIB port number is 7, and the default
address for the sweeper is 19, so the device selector is 719.

Clear
Clear causes all GPIB instruments, or addressed instruments, to assume a
\cleared" condition, with the denition of \cleared" being unique for each
device.For the sweeper:
1. All pending output-parameter operations are halted.
2. The parser (the software that interprets the programming codes) is reset,
and now expects to receive the rst character of a programming code.
The syntax is:

Output is used to send function commands and data commands from the
controller to the addressed instrument. The syntax is:

way, such as a binary or ASCII representation of numbers

output; these image items can be a string of code characters
to a statement line in the computer program. Image items are explained in
the programming codes where they are needed. Notice that this syntax is
