CONNECTORS
HP-IB connector allows the swept signal generator 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 swept
signal generator (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
adrs
for information on setting
the swept signal generator’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 37201A, 37204A/B) that overcome the range limitations
imposed by the cabling rules. These extenders allow twin-pair cable
