MASS-08/MASS-08A Universal Echo Precision Delay Component (Universal Continuous Analog)

The MASS-08/MASS-08A Universal Echo Precision Delay Component (Universal Continuous Analog) is a high-performance aerospace device engineered for precise, continuous analog delay of echo signals, tailored to test and calibrate radio altimeters across FM, PM, and pulse modulation systems. It enables accurate simulation of terrain-relative altitude scenarios—with the MASS-08 covering 0–2000m and the MASS-08A extending to 0–8000m—featuring 0.5m resolution and reliable precision even at varying heights. Compliant with rigorous operational standards, it offers strong interference suppression (e.g., ≥80dB transceiver isolation) and stable performance across wide temperature ranges, making it ideal for pre-flight validation and maintenance of commercial and special aircraft avionic systems.
