HP 37203A / Agilent 37203A HP-IB / GP-IB Extender with OPT. 001

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 Option 001 adds a fibre optic transmitter and fibre optic receiver to the standard 37203A. This provides the capability of extending the HP-IB over either dual fibre optic cable or coaxial cable. The 37203A Option 001 transmits the bit serial stream over dual fibre optic cable for distances up to 1000 metres. It enables a higher HP-IB data-byte transfer rate to be attained for transmission distances greater than 250 metres than is possible with the standard 37203A. The fibre optic cable removes the metallic connection between the bus extenders and therefore eliminates any electromagnetic pick-up on the serial link. Option 001 is recommended for use in severe electrical environments or where the use of electrical signalling is not acceptable.
