DESCRIPTION
The Rockwell Collins DME-2100 gives you unparalleled scanning performance,
while actually decreasing ground station loading. The DME-2100 benefits from moving from analog to digital technology
by using minimal analog circuitry and a lower overall component count, which
increases the overall reliability of the system. The 20% lower power consumption
allows the DME-2100 to not require forced air cooling and reduces the total
weight by 25% of similar DMEs. The DME-2100 has been designed to provide highly accurate distance data
outputs in all modes of operation. Error sources in the interrogator are
identified and reduced to the lowest level. In addition, optimum methods
in all modes of operation reduce naturally occurring noise contained in the
DME/TACAN signal and improved ident algorithm. A comprehensive self-test monitor is capable of determining its operational
status to a better than 99% confidence level. The DME-2100 Receiver meets all essential level HIRF requirements, provides
improved power interrupt capability, lower power consumption and enhanced
BITE interface for Airbus aircraft.
