Satellite Link Emulator series

The Polaris PSLE series is a Satellite Link Emulator for geostationary satellites. The PSLE series provides an ideal solution for satellite modem testing, satellite to Earth station RF link testing, spacecraft payload testing, and general testing systems using satellite communications. The PSLE series is categorized into an IF band series and a L band series. The IF-band series operates at 70MHz or 140MHz, and the L-band series operates from 950MHz to 1,450MHz (950MHz to 1,950MHz optional).

The PSLE series provides three types of simulations.

●  Time Delay
Simulation for propagation time delay due to distance between satellite and earth station terminals

●  Doppler Effect
Simulation for Doppler frequency shifts between satellite and moving earth station terminals

●  Attenuation
Simulation for radio path loss due to heavy rain or heavy snow


RF Switch Matrix series

The Polaris SW08-DP Switch Matrix provides automatic routing between Vector Network Analyzer and the device under test (DUT) in an RF/microwave ATE system. This Switch Matrix provides consistent signal paths, enable automation of tests.

The SW08-DP can support up to 8 switch channels in a 1U rack-mountable enclosure with signal frequencies up to 8 GHz. It is possible to expand the switch channels by connecting two SW08-DPs to master or slave, respectively, and to support up to 16 switch channels in a 1U rack. The SW08-DP provides a cost effective and quick-ship solution with a simple and flexible platform.
