Satellite Link Emulator

The Satellite Link Emulator from dBm provides a cost effective, time-saving, repeatable total solution for satellite to ground station RF link testing. Accurate simulation of propagation delays, flat fading, path loss, phase shift and Doppler shifts let systems engineers create realistic, full-duplex path scenarios for closed-loop testing of satellites, ground processing equipment, and mobile transceivers. The SLE may be configured with up to four independent channels and operates at a centre frequency of 140 MHz (optional 70 MHz, and L, C, S and K-band with optional RF converters)

Test parameters can be entered via the front panel, by downloading files from internal flash memory or by downloading data through the Ethernet port.

The SLE simplifies VSAT earth terminal testing and satellite channel impairment testing for Low Earth Orbit, Medium Earth Orbit, Geostationary and Geosynchronous systems and has been deployed on all the major satellite programs worldwide. The SLE is also optimised to operate with dBm's CNG series of precision carrier to noise generators, thereby allowing precisely controlled noise to be added to the RF link.
