Parrot IS-95 CDMA Channel Simulator

The Parrot™ consists of 6 (or more) IS-95 CDMA channels, each individually controlled by an external (host) PC. Each CDMA channel consists of three orthogonal channels. The three channels are digitally combined with user defined ratio. For instance, pilot, sync, traffic or page. For each CDMA channel, the data content, RF amplitude and carrier frequency can be independently set on any 1.25 MHz bandwidth. In addition, each channel can be programmed to produce signal amplitude variations (fading) ± 16 dB of its output level using preprogrammed algorithms such as Raleigh fading or other models at rates up to an equivalent vehicle speed of 100 MPH.

The data parameters of each channel along with its associated RF level can be set to any required level. The "peak to valley" difference between any output can be as large as 40 dB. Individual channel amplitude output levels are regulated to within ± 2 dB. Each channel is brought to the front panel via an N connector and the combined channel RF amplitude has an output range greater than 80 dB.
