Description
Polaris’ ASLE series is an advanced satellite link emulator designed to extend the propagation time delay of the PSLE series from 265ms to 530ms. The ASLE-L series operates in L-band and supports Doppler shift of up to -6MHz to 6MHz and operating bandwidth of up to 200MHz.
The ASLE-L series provides accurate reproductions for propagation time delay, path loss, and doppler frequency shift for closed-loop testing of geostationary satellites and earth station terminals.
