Delay lines are essential hardware items for applications requiring time delay as part of systems test and / or evaluation. Microwave Photonic Systems Fiber Optic Delay lines have long been trusted elements of Radar Testing, Software Defined Radio Signal Processing, Phased Antenna Array Testing as well as for complex attribute generation as part of a complex EW and SIGNIT topography. MPS’s delay line product offering is scalable to the customers’ requirements and can be configured as a fixed delay line or a switchable delay line. Packages include small form factor to large multi-rack chassis that can be further expansible with the addition of external delay ports. All delay lines can take advantage of MPS’s microwave components such as integrated Low Nosie Amplifiers, Post Amplifiers, Automatic Gain Control, as well as Remote Ethernet Switch Control and Diagnostic Monitoring.
