Printing History
New editions are complete revisions of the manual. Update packages,
which are issued between editions, contain additional and replacement
pages to be merged into the manual by the customer. The dates on the
title page change only when a new edition or a new update is published.
No information is incorporated into a reprinting unless it appears as a
prior update; the edition does not change when an update is incorporated.
A software code may be printed before the date; this indicates the version
level of the software product at the time of the manual or update was
issued. Many product updates and fmes do not require manual changes
and, conversely, manual corrections may be done without accompanying
product changes. Therefore, do not expect a one to one correspondence
between product updates and manual updates.

List of Effective Pages
The List of Effective Pages gives the data of the current edition and of any
pages changed in updates to that edition. Within the manual, any page
changed since the last edition will have the date the changes were made
printed on the bottom of the page. If an update is incorporated when a
new edition of the manual is printed, the change dates are removed from
the bottom of the pages and the new edition date is listed in Printing
History and on the title page.

Introductionto
Programming an Instrument

Introduction This chapter introduces you to the basics of remote programming. The
programming instructions explained in this book conform to the
IEEE 488.2 Standard Digital Interface for Programmable
Instrumentation. These programming instructions provide a means of
remotely controlling the HP 1652B/53B. There are three general
categories of use. You can:
l Set up the instrument and start measurements
l Retrieve setup information and measurement results
l Send measurement data to the instrument
The instructions listed in this manual give you access to the measurements
and front panel features of the HP 1652B153B. The complexity of your
programs and the tasks they accomplish are limited only by your
imagination. This progr amming reference is designed to provide a
concise description of each instruction.
About This
Manual
This manual is organized in 27 chapters. Chapter 1 is divided into two
sections. The first section (pages 2 through 9) concentrates on program
syntax, and the second section (pages 10 through 17) discusses
programming an instrument. Read either chapter 2, “Programming Over
HP-IB,” or chapter 3, “Programminn Over RS-232C” for information
concerning the physical connection between the HP 1652B/53B and your
controller. Chapter 4, “Programming and Documentation Conventions,”
gives an overview of all instructions and also explains the notation
conventions used in our syntax definitions and examples. The remaining
chapters 5 through 27 are used to explain each group of instructions.

Programming
Syntax
Talking to the In general, computers acting as controllers communicate with the
Instrument instrument by sending and receiving messages over a remote interface,
such as HP-IB or RS-232C. Instructions for programming the HP
1652B/53B will normally appear as ASCII character strings embedded
inside the output statements of a “host” language available on your
controller. The host language’s input statements are used to read in
responses from the HP 1652B/53B.
For example, HP 9000 Series 2W300 BASIC uses the OUTPUT
statement for sending commands and queries to the HP 1652B/53B. After
a query is sent, the response is usually read in using the ENTER
statement. All programming examples in this manual are presented in
BASIC. The following BASIC statement sends a command which causes
the HP 1652B/53B’s machine 1 to be a state analyzer:
OUTPUT XXX:":MACHINEl:TYPE STATE" <terminator>
Each part of the above statement is explained in the following pages.
Instruction Syntax To program the instrument remotely, you must have an understanding of
the command format and structure expected by the instrument. The IEEE
483.2 syntax rules govern how individual elements such as headers,
separators, parameters and terminators may be grouped together to form
complete instructions. Syntax definitions are also given to show how
query responses will be formatted. Fiie l-l shows the main syntactical
parts of a typical program statement.

Progmmmlng Reference

OutputCommand The output command is entirely dependant on the language you choose to
use. Throughout this manual HP !%OO Series 2W300 BASIC 4.0 is used in
the programming examples. People using another language will need to
find the equivalents of BASIC commands like OUTPUT, ENTER and
CLEAR in order to convert the examples. The instructions for the
HP 1652B/53B are always shown between the double-quotes.
Device Address The location where the device address must be specified is also dependent
on the host language which you are using. In some languages, this could
be specified outside the output command. In BASIC, this is always
specified after the keyword OUTPUT. The examples in this manual use a
generic address of XXX. When writing programs, the number you use
will depend on the cable you use in addition to the actual address. If you
are using an HP-IB, see chapter 2. RS-232C users should refer to
chapter 3, “Programming Over RS-232C.”
Instructions Instructions (both commands and queries) normally appear as a string
embedded in a statement of your host language, such as BASIC, Pascal or
C. The only time a parameter is not meant to be expressed as a string is
when the instruction’s syntax definition specifies <block data >. There
are only five instructions which use block data.
Instructions are composed of two main parts: The header, which specifies
the command or query to be sent; and the parameters, which provide
additional data needed to clarify the meaning of the instruction.
instruction Header The instruction header is one or more keywords separated by colons (:).
The command tree in figure 4-l illustrates how all the keywords can be
joined together to form a complete header (see chapter 4, “Programming
and Documentation Conventions”).
The example in figure l-l shows a command. Queries are indicated by
adding a question mark (?) to the end of the header. Many instructions
can be used as either commands or queries, depending on whether or not
you have included the question mark. The command and query forms of
an instruction usually have different parameters. Many queries do not use
any parameters.
When you look up a query in this programming reference, you’ll fmd a
paragraph labeled “Returned Format” under the one labeled “Query
Syntax.” The syntax definition by “Returned format” will always show the
instruction header in square brackets, like (:SYSTem:MENU]. What this

Header Types
really means is that the text between the brackets is optional, but it’s also a
quick way to see what the header looks like.
White space is used to separate the instruction header from the
instruction parameters. If the instruction does not use any parameters,
you do not need to include any white space. White space is defined as one
or more spaces. ASCII defines a space to be character 32 (in decimal).
Tabs can be used only if your controller first converts them to space
characters before sending the string to the instrument.
Instruction parameters are used to clarify the meaning of the command or
query. They provide necessary data, such as whether a function should be
on or off, which waveform is to be displayed, or which pattern is to be
looked for. Each instruction’s syntax deli&ion shows the parameters, as
well as the values they accept. This chapter’s “Parameter Syntax Rules”
section has all of the general rules about acceptable values.
When there is more than one parameter they are separated by
commas (,). You are allowed to add spaces around the commas.
There are three types of headers: Simple Command; Compound
Command; and Common Command.
Simple Command Header. Simple command headers contain a single
keyword. START and STOP are examples of simple command headers
typically used in this instrument. The syntax is:
cfunction > c terminator >
When parameters (indicated by c data z= ) must be included with the
simple command header (for example, :RMODE SINGLE) the syntax is:
cfunction> cwhits space > <data> cterminator >
Compound Command Header. Compound command headers are a
combination of two or more program keywords. The first keyword selects
the subsystem, and the last keyword selects the function within that
subsystem. Sometimes you may need to list more than one subsystem
before being allowed to specify the function. The keywords within the
compound header are separated by colons. For example:
To execute a single function within a subsystem, use the following:
