CONNECTORS

HP-IBconnector 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.

User’s Handbook

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:

nEach instrument must have a unique HP-IB address, ranging from 0 to 30 (decimal). Refer to 8360 adrs for information on setting the synthesizer’s HP-IB address.

nIn a two-instrument system that uses just one HP-IB cable, the cable length must not exceed 4 meters (13 ft).

nWhen 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.

nThe total cable length between all units must not exceed 20 meters (65 ft).

Hewlett-Packard manufactures HP-IB extender instruments

(HP models 372OlA, 37204A/B) that overcome the range limitations imposed by the cabling rules. These extenders allow twin-pair cable
