The Telemetrix® 400 Channel Simulator (T400CS) creates RF and IF signals matching those occurring when transmitters and receivers are in motion with respect to one another. Channel effects include smooth, phase-continuous carrier and signal Doppler shift, range delay, range attenuation, fading, and noise. Multiple test and/or interference signals also can be generated.

A set of frequency up/downconverters enables signals to be generated or received at RF. The T400CS can be cable connected to DUTs or produce short-range or long-range on-air signals using amplifiers, signal conditioners, and antennas.

Local control is provided by the company’s client software; remote-control capabilities include Analytical Graphics’ STK software and user-written applications sending ASCII and binary commands over an Ethernet connection to the instrument. Users also may develop channel simulation profile files.
