概述

ADVANCED CHANNEL EMULATOR - ACE9600 builds upon the SLE900 by adding Payload impairment capability, synchronization of up to 16 channels, 12 tap multipath fading, and 600 MHz of instantaneous bandwidth. The instrument can be configured with 1 to 4 channels. Link impairments include delay, Doppler, attenuation, phase offset, AWGN, frequency hopping, and multipath fading. Payload impairments include IMUX/OMUX emulation (amplitude and delay distortion), amplifer compression effects (AM/AM and AM/PM), phase noise, and spurious signals. Parameters can be set to fixed values in Static mode, or continuously changed in real time in Dynamic mode without 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 executed single run, continuously looped, or single stepped.
