Description

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 in general testing systems using satellite communications. The PSLE series is classified into IF band series and 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). In addition, the L-band series is categorized into a models operating in a wide band and a models operating in a narrow band.
The PSLE series provides the following three types of simulation.

●  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

Features

●  Built-in L-band Frequency Converters (PSLE-L series)
●  Ultra-wide Bandwidth up to 200MHz (PSLE-L-200D)
●  Complete simulation without BER deterioration for signals with high modulation index
●  Excellent Phase Noise
●  Excellent SNR using 14bit ADC
●  Spurious suppression higher than 50dBc in out-of-band (40dBc for PSLE-L-200D)
●  Superior quality proven by domestic and foreign defense companies
