HP-IB stands for Hewlett-Packard Interface Bus, and is often
referred to as the bus. It is Hewlett-Packard’s implementation of the
IEEE 488.1-1987 and the IEEE 488.2-1987 Standard Digital Interface
for Programmable Instrumentation.
All functions are programmable except the front panel power key,
knobs, increment set key, arrow keys, frequency reference keys and
the rear panel display contrast control.
The HP-IB address for the signal generator is set to 19 at the factory.
It may be changed to any address from 00 through 30 by pressing
IADRS) and the desired two-digit number.
The HP-IB programming error messages are described in Chapter lc,
“Operation Messages. n
Although many system controllers and programming software
languages are compatible with this instrument, all examples and
references in this manual assume the use of an HP controller utilizing
the HP BASIC programming language.
Most instrument settings may be queried via HP-IB. The data returned
from the query will vary from a yes/no (l/O) to the actual setting,
depending on the function. See Table 2-l.
For the majority of applications, remotely programming the signal
generator requires only basic programming knowledge and the
command statements listed later in this chapter. Developing
programs for querying the instrument’s status is considered to be
an advanced application. (See “HP-IB Status Reporting.“) For more
information on HP-IB programming see the Tutorial Description of the
Hewlett-Rzckard Interface BUS (HP part number 5952-0156).
