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-L-200D provides accurate simulation for propagation delay, path loss, and Doppler frequency shift for closed-loop testing of geostationary satellites and earth station terminals. The ASLE-L-200D operates from 950MHz to 1,450MHz and provides up to 200 MHz bandwidth.
