The ALT‑8000 FMCW/Pulse Radio Altimeter Test Set features a 12‑inch sunlight‑readable touchscreen display and TX/RX antenna couplers with 0–19.9 dB loss compensation. It provides direct TX/RX ports with 50‑ohm impedance, SWR of 2.5:1 (TX) and 3:1 (RX), using dual TNC connectors. The receiver supports 4.20–4.40 GHz FMCW operation with ±5 MHz frequency measurement accuracy. It tracks RF input power from +10 dBm to +33 dBm and measures TX power from +6 dBm to +33 dBm with ±2 dB accuracy. It also measures FM sweep rates from 50–400 Hz with ±5 Hz accuracy and FM deviation from 20–100 MHz, ensuring precise, reliable altimeter testing.
