Description

Polaris’ ASLE series products are satellite link emulators for geostationary satellites and provide 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 ASLE series products are categorized into IF-band emulators and L-band emulator. The IF-band emulators operate at 70MHz or 140MHz and the L-band emulator operates from 950 MHz to 1,450 MHz (950 MHz to 1,950 MHz optional).
The ASLE series ptoducts provide reproductions for three types of satellite links.

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

●  Doppler Effect
Reproduction for doppler frequency shift between satellite and moving earth station terminals

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