Model 6067 Digital Altimeter Test Set

System Description
The Model 6067 Digital Radar Altimeter Test System is a precision RF simulation platform engineered to replicate real-world altitude conditions for radar altimeters in a controlled, repeatable lab environment. Operating within the 4.2–4.4 GHz band, the system emulates ground-return signals by applying highly accurate, programmable time delay – effectively translating delay into altitude across a wide range from very low-level flight through high-altitude scenarios. This enables comprehensive verification and calibration of radar altimeters without the cost, variability, or logistical burden of flight testing.

At the core of the system is a fully digital delay architecture that delivers smooth, continuous altitude simulation with fine resolution and high accuracy. The Model 6067 goes beyond basic delay generation by incorporating advanced RF conditioning and signal control, allowing users to precisely adjust amplitude, balance, and isolation to match real-world conditions. Integrated features such as antenna installation delay (AID) simulation further enhance realism by accounting for platform-specific offsets.

In addition to altitude simulation, the system provides robust environmental modeling capabilities, including multi-path reflections, Doppler effects, and clutter or interference scenarios – enabling engineers to evaluate performance under both nominal and edge-case conditions. With flexible operation via front panel controls or full remote automation using standard SCPI interfaces, the Model 6067 integrates seamlessly into ATE environments for production, depot calibration, and R&D workflows.
