- The SLE900 replaces the SLE700 and provides wider bandwidth, improved noise floor, and also adds optional AWGN and multipath fading with up to 6 taps per channel. The instrument can be configured with 1 to 4 channels. There are three RF bandwidths currently available: 72 MHz bandwidth centered at either 70 MHz or 140 MHz, 125 MHz bandwidth centered at 140 MHz, and 250 MHz bandwidth centered at 1200 MHz. Link impairments include delay, Doppler, attenuation, phase offset, AWGN, and multipath. Parameters can be set to fixed values in Static mode, or continuously changed in real time in Dynamic mode without any phase discontinuities. Ephemeris data files are downloaded via an ethernet connection and stored internally in solid state memory. These dynamic files can have playback rates from 1 Hz to 1000 Hz, and can be run forward, reverse, continuously looped, or single stepped.
