The TB_DVOR test rack supports both intelligent modules (keyer/interface units, local status indicators) and slave modules (mains power supplies, pulse filters, RF combiners), encompassing over 15 distinct LRUs in one rack.

Every DVOR module validated on the bench, not discovered out of tolerance in the field.

Built-in BIT and guided fault-location routines run start-up self-diagnostics across power, signal, and communication lines, reducing mean-time-to-repair by up to 40%. Pre-configured scripts drive RF stimulation, DC power stress tests, and waveform captures; results are auto-logged in a centralized database with instant PDF report generation.

Architecture

Three subsystems, one cabinet.

The TB_DVOR is structured into three optimized subsystems working together from a single IP65-rated 19″ rack.

Rugged, resilient design

MIL-grade cabling and connectors, an IP65-rated weatherproof enclosure, anti-glare touch display, and a 20-minute UPS backup keep full test continuity through grid failures. The rack is built to CE and MIL-STD-810 shock/vibration standards for reliable shop-floor operation.

The RF generator emulates rotating-antenna Doppler modulation across 960–1250 MHz at up to +8 dBm, ensuring azimuth accuracy testing consistent with ICAO Annex 10 aeronautical telecommunications standards.

Principle of Operation

Five stages, every module.

From power-up self-checks through report compilation, each DVOR module follows the same automated sequence.
