"Designed for optimum efficiency and durability, our HPIB/GPIB cables ensure flawless data transmission and are manufactured according the IEEE-488 specification. They feature male and female piggy-backed 24-pin Centronics style connections to allow daisy-chaining to another instrument or printing device. Each cable is double-shielded and fully molded to reduce EMI/RFI interference and achieve maximum signal integrity. The GPIB bus was invented by Hewlett Packard at the end of the 1960's. The intention was to create a reliable bus system especially designed for connecting computers and instruments. This networked system has all features that are required to create a measurement system. Remote control of instruments is one aspect of these features, but there are other more important features like data handshake for reliable operation and real-time response capability, only to name a few. The original bus system, designed by Hewlett Packard, was called HPIB, short for Hewlett Packard Interface Bus. Connectors: Centronics 24-pin Male/Female to Centronics 24-pin Male/Female. Specified Transfer Rate: 1 MByte per second. Up to 15 instruments (devices) can be connected to one computer (controller). Cable Length: 20m between controller and one device or 2m between each device, whichever is less. Data Transfer Mode: 8 bit parallel. Designed for: Connecting computers and instruments."
