Astronics Test Systems Inc. Racal Instruments™ 1260-138A High-Density Multiplexer Plug-In The Racal Instruments™ 1260-138A is a high-density scanner/multiplexer switch card for use in Racal Instruments™ 1260-100 and 1260-101 VXI carriers or the Racal Instruments™ 1256 GPIB/Ethernet and 1256L (LXI Core 2011 Compliant) switching systems. Key Features • Eight 1x8, two-wire scanner/ multiplexer • Link 1x8 cells under program control • Link up to 6 plug-ins under program control • Can be used in VXI, GPIB/RS-232, and LXI switching systems • True differential design ideal for telecom and datacom applications • Two and four-wire switching modes • Standard Adapt-a-Switch™ plug-in design for ease of replacement Product Information This plug-in provides maximum flexibility to construct a wide range of scanner/ multiplexer configurations under software control while maintaining excellent bandwidth and signal integrity. All relays are bi-directional, enabling use as either a scanner or multiplexer. Each (1x8) multiplexer can be used to connect any combination of up to 8 two-wire signals to a two-wire common. These commons can be linked under program control to construct any combination of larger multiplexers. Possible configurations include: • One (1x64) two-wire • Two (1x32) two-wire • Four (1x16) two-wire • One (1x16) two-wire plus One (1x48) two-wire • Many other configurations Multiple plug-ins can be linked under program control via the Adapt-a-Switch™ carrier or 1256 analog bus to form large two- and four-wire multiplexers. This allows you to construct very large multiplexers without external wiring. It also eases the integration/wiring task while maintaining signal integrity. This card was designed for true differential switching, which makes it ideal for telecom and datacom applications. However, it has great single ended characteristics as well with >85 MHz bandwidth. With its combination of density, versatility, expandability, and high signal integrity, the 1260-138A is ideal for construction of large switching systems, as well as applications where the final switching requirements are not fully defined. The 1260-138A is an excellent choice for continuity testing, audio, video, telecom, datacom, and multipurpose ATE systems. The Racal Instruments™ Option 01T interface (for VXI) controls the 1260-138A using either register-based or message-based commands. The 1256 (for GPIB/ Ethernet) and 256L (for LXI) support message-based operations.
