CONNECTORS
HP-IB
connector allows the synthesizer to be connected to any other
instrument or device on the interface bus. All HP-IB instruments
can be connected with HP-IB cables and adapters. These cables are
shown in the accompanying illustration. The adapters are principally
extension devices for instruments that have recessed or crowded
HP-IB connectors.

As many as 14 HP-IB instruments can be connected to the
synthesizer (15 total instruments in the system). The cables can be
interconnected in a “star” pattern (one central instrument, with
the HP-IB cables emanating from that instrument like spokes on
a wheel), or in a linear pattern (like boxcars on a train), or any
combination pattern. There are certain restrictions:
n
Each instrument must have a unique HP-IB address, ranging from
0 to 30 (decimal). Refer to
8360
for information on setting
the synthesizer’s HP-IB address.
n
In a two-instrument system that uses just one HP-IB cable, the
cable length must not exceed 4 meters (13 ft).
n
When more than two instruments are connected on the bus, the
cable length to each instrument must not exceed 2 meters (6.5 ft)
per unit.
n
The total cable length between all units must not exceed 20 meters
(65
ft).
Hewlett-Packard manufactures HP-IB extender instruments
(HP models
that overcome the range limitations
imposed by the cabling rules. These extenders allow twin-pair cable
