HP 8340b Operating Instructions

Controller
A controller is an instrument, typically a computer, that is capable of managing the various HP-IB
activities. Only one device at a time can be an active controller.
PROGRAMMING THE HP 8340B/41B
The HP 8340B/41B can be entirely controlled by a computer (although the line POWER switch must be
operated manually). All functions that are initiated by front panel keystrokes (local operation) can also
be initiated by an HP-IB computer additionally, several functions are possible only by computer
(remote) control. Computer programming procedures for the HP 8340B/41B involve selecting an HP-
IB command statement, then adding the specific HP 8340B/41B 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 the unique codes that have no front panel
equivalent.
In the programming explanations that follow, specific examples are included that are written in a
generic dialect of the BASIC language. BASIC was selected because the majority of HP-IB computers
have BASIC language capability; however, other languages can also be used. Hewlett-Packard pub¬
lishes a series of Programming Notes that contain computer-specific, language-specific information
for those wishing to use another language; contact the nearest HP Sales and Service Office (listed
inside of the back cover) for a list of HP 8340B/41B Programming Notes.
HP-IB COMMAND STATEMENTS
Command statements form the nucleus of HP-IB programming; they are understood by all instru¬
ments in the network and, when combined with instrument-specific codes, they provide all manage¬
ment and data communications instructions for the system.
An explanation of the fundamental command statements follows. However, some computers use a
slightly different terminology, or support an extended or enhanced version of these commands. Con¬
sider the following explanations as a starting point, but for detailed information consult the BASIC
language reference manual, the I/O programming guide, and the HP-IB manual for the particular
computer being used.
Syntax drawings accompany each statement: All items enclosed by a circle or oval are computer-
specific terms that must be enterd 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.
