Aeroflex, Inc. announces its 6401 AIME 3G mobile protocol test system. The device integrates RF-based radio channel emulation methods by integrating them at baseband. Applying the time varying radio channel characteristics digitally, facilitates high accuracy combined with repeatability, essential for thorough testing of the physical layer of 3 G devices. With the device’s integrated radio channel fading capability, up to eight paths for each of its three UMTS carriers are available. This allows multi-path conditions to be simulated with each path independently controlled to provide either constant, Rayleigh, Doppler, periodic or log-normal gain and constant, periodic or pseudo-random delay conditions.
