Eastern OptX announces Series 7000 Multi-Radio Channel Replicator

Eastern OptX, specialists in fiber optic delay lines for RF and microwave test applications, announced the commercial availability of the Series 7000 Multi-Radio Channel Replicator, a multi-radio test system that replicates the propagation path of real-world applications. The Series 7000 is used by the radio communications industry to design, produce, qualify, and verify interoperability of radio systems. It brings the realistic conditions of an outdoor test range into the test laboratory while reducing--and in some cases--completely eliminating time-consuming and expensive outdoor testing.

The Series 7000 is used as a design aid and test tool for new modulation and encryption schemes. Unlike radio emulators on the market today that produce a waveform based on expected output for given input, the Series 7000 requires no a priori information about signal waveform, frequency range, encryption, data rate, power level, frequency agility, or modulation scheme.

Radio System Optimization and Troubleshooting in a Lab

The Series 7000 multi-radio test system allows users to test a variety of air interfaces using the same system without modification, and at the same time. Eastern OptX uses low-loss fiber optic cable to create the propagation delay associated with radio transmissions from 1 to 5000 MHz. Multiple radios can be connected to the network, allowing full duplex operation. Each radio may operate using a different or identical air interface. The delays between the radios can be variable or fixed. Optional amplitude control provides the appropriate propagation loss.

Key features of the system include automatic propagation loss replication, options for multi-path and Doppler (for moving targets), and better than 1% NIST traceable accuracy. Additional advantages of the Series 7000 include:
