1-3. WHERE TO FIND SAFETY CONSlDERATIONS
This prod\lct is a Safety Class I instrument; that is, one provided with a protective earth terminal.
Before operating or servicing the Signal Generator, service personnel should familiarize
themselves with the safety markings on the Signal Generator and the safety instructions. Safety
information pertinent to the task at hand (that is, information regarding installing, operating,
performance testing, adjusting, or servicing the HP 8642A/B) is found throughout this manual.
Refer to the Safety Considerations pages found at the beginning of Volume I for a summary of
that information
1-4. HEWLETT-PACKARD INTERFACE BUS (HP-IB) ENABLES REMOTE CONTROL OF
THE INSTRUMENT . . .
The HP 8642A/B Signal Generator has a Hewlett-Packard Interface Bus (HP-IB) interface and
can be used with an HP-IB compatible controller for test system applications. The Signal
Generator is fully programmable via the HP Interface Bus HP-IB is Hewlett-Packard's
implementation of IEEE Standard 488 and the identical ANSI Standard MC 1.1. (Refer to the
HP-JB portion of Section 1II for more complete details.)
Selecting the HP-IB Address
The Signal Generator's HP-IB address is set to 19 at llle factory in both internal memory and an
in ternal switch loea ted inside the instrument. The decimal equi valent of the 5 - bit address code
can be displayed on and changed from the front panel. Refer to HP-Ill Address in the HP-IB
portion of Section III for information regarding changing the HP-IB address.
lIP-IB Capabilities
This Signal Generator's HP-IB capabilities are defined by the following list of interface
functions. For more information, refer to page
