ATC/DME Signal Generator

The SDX 2000 from JcAIR Test Systems is a fully programmable RF tester for all commercial and military pulsed L-band avionics including ATCRBS and Mode-S transponder (including datalink), DME, TACAN, and IFF (Identify Friend or Foe).

General features include:

color, active-matrix LCD display;

graphical user interface via acoustic wave touch-sensitive screen;

pop-up menus;

integral solid-state disk drive for storing commonly used test sequences and semi-automated testing;

digital signal processing technology to improve reliability and reduce calibration requirements;

dual, independent L-Band generators simulate true "signal-in-space" for diversity testing;

fully GPIB programmable for ATE applications;

measures 10.7 in H, 17.65 in W (19 in rack mount), 20.5 in D with handles (19.7 in rack);

and power requirements are 93 to 264 VAC/45 to 440 Hz.
