The ADF‑2000L is a fully digital aviation signal source specifically designed for testing and calibrating aviation navigation equipment. It can simulate ADF (Automatic Direction Finder) signals commonly used in aviation navigation systems, helping users verify the performance and reliability of navigation equipment. It is suitable for civil aviation maintenance, avionics R&D, flight training, and other related fields.
ADF carrier signal generation
Set the frequency and amplitude parameters of the ADF carrier signal via the touchscreen to generate an ADF navigation signal that complies with international standards, testing the carrier reception performance of the ADF receiver.
Bearing angle simulation
Set the bearing angle (heading) via the touchscreen. Using the sin and cos reference signals from the ADF receiver, simulate the ADF carrier signal (containing heading angle information) received by the combined antenna, testing the direction‑finding performance of the ADF receiver.
Additional audio signal simulation
Set parameters such as the frequency, modulation depth, and additional Morse code information of the additional audio signal via the touchscreen, then modulate it onto the ADF carrier signal to test the audio demodulation performance of the ADF receiver. Both single‑tone modulation and Morse code modulation are configurable.
High‑precision simulation – All‑digital synthesis of combined antenna signals, simulating various bearing angles (0–359°).
Dual‑channel output – Two independent signal sources allow simultaneous testing of two ADF receivers.
Touchscreen control – Conveniently set signal frequency, amplitude, modulation depth, bearing angle, audio signal, and other parameters.
Intelligent output adjustment – Built‑in high‑precision power meter for real‑time measurement and automatic fine‑tuning, ensuring output signal accuracy.
Strong compatibility – Supports TCP/IP protocol and includes a complete SCPI command set, enabling integration into existing aviation test systems.
