GPIB Extenders & Isolators

GPIB Bus Switch and Multiplexer

● Operates as a 1:2 or 1:3 bus switch, permitting a single controller to operate three IEEE 488 Bus systems and up to 39 devices. Expands the number of instruments beyond the IEEE 488 limits.
● Operates as a 2:1 or 3:1 multiplexer so up to three bus controllers can share a common IEEE 488 bus, instruments, or GPIB peripherals. Time-shares expensive equipment.
● Cascadeable for large system applications. Easy expansion to nine buses.
● High data-transfer rate and minimum signal delays. Does not degrade system performance.
● Each bus controller can poll the 4842's status to determine availability of shared instruments or peripherals. Find out what's happening on the remote bus.
● Reservation stack with automatic SRQ to next controller. Reserves your turn with the shared equipment.
● IEEE-488.2 compatible unit uses SCPI commands. Uses standardized commands
for easy programming.

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.
