GPIB Bus Expander/Isolator

● Provides over 2000 V isolation between instruments and bus controller. Eliminates ground loops, noise and associated data errors.
● Allows more than 14 devices on the GPIB bus. Overcomes the bus drive limitation.
● Extends the bus length an additional 20 meters. Overcomes the bus length limitation.
● No false responses to the FindLstn Protocol. Supports all IEEE 488.2 protocols.
● Invisible to the IEEE 488 Bus controller. Needs no bus address or special programming.
● Fast handshake rate. Doesn't slow your system.
● Front panel indicators show controller and talker locations. Visual operating status.
● Small metal case provides EMI/RFI protection. Proven EMI/RFI Compliance.

 

Brochure EN

The Model 4862A Bus Expander is for those applications requiring only additional bus drive capability. Because the 4862A output signals are not isolated, some internal delay times are reducedto minimal values. All other performance features are identical to the Model 4860A.
