HP-Agilent/Keysight HP 37203A

The 37203A may be connected directly to a maximum of 14 other HP-IB devices subject to the normal cabling restrictions imposed by the interface standard. It will provide extension for the full range of HP-IB functions. The 37203A HP-IB Extender overcomes the range limitations imposed by the cabling rules of the Interface Bus and provides high-speed (up to 50 k bytes/S), low-cost extension up to 1000 meters. 37203A’s are used in pairs, each Extender serializes the normally parallel HP-IB information and transmits it to the other Extender where it is reconverted back to its original format.
