The 7703R4x1-RF are bi-directional, low loss switches for signals from DC to 3GHz. Control of the switch may be done locally at the card-edge with the built-in rotary encoder and dot-matrix display, or remotely through SNMP/VistaLINK®. Applications include selecting from multiple signal sources and routing one to a piece of instrumentation such as an oscilloscope, spectrum analyzer or other signal analysis/monitoring equipment. Similarly, a single signal source may be routed to any one of multiple connected receiving devices for applications such as antenna switching. The 7703R4x1-RF are ideal for use any facility where signal switching is required, or in automated testing applications. The 7703R4x1-RF occupies one card slot.
