The CIMS Digital Recording and Analysis System (D-RAS) provides long term recording capabilities for analogue signals and the offline analysis of the recorded data. A D-RAS version is currently used as CORAL by DFS Deutsche Flugsicherung GmbH.
D-RAS allows to record between 1 and 4 analogue signals on a digital storage medium. The digital recording method prevents any degradation of the recorded signals.
After the recording the data can be evaluated by the D-RAS analysis facility. The analysis functions can be customised to satisfy any particular evaluation requirements. As a basic means an oscilloscope display is provided which allows to view arbitrary intervals of the recorded signals in the time domain.
Two channels can be viewed simultaneously.
Navigation elements allow to navigate through the hours of recorded data and view any particular interval.
By means of search functions particular events or times can be found in the data sets. Dedicated search functions for more complex signal patterns can be implemented in accordance with customer requirements.

CIMS Engineering & Systmes GmbH offers the development of dedicated testequipment.
A few examples are listed below
Within the scope of a contract with DFS Deutsche Flugsicherung GmbH we recently performed a comparative performance analysis of the sub-networks that are being developed in support of the Aeronautical Telecommunication Network ATN.
These are the Mode S Subnetwork, the Aeronautical Mobile Satellite Service AMSS and VDL Data Link Modes 2 and 4. Our responsibilities included concept definition, the specification and development of the required test- tools, the development of test scripts and the evaluation of test result data.
At the time that the test campaign was initiated the sub-networks had been functionally verified in great detail. However knowledge of their operational performance was insufficient and it was our task to create a test campaign that provided the missing information.
An essential element of the test campaign was the development of the Data Link Processing Analyser.
This tool facilitated the measurement of the parameters of each data link in a uniform manner, so providing truly comparable test results. The test result data obtained in a combination of laboratory and flight trials was analysed using our purpose-built software tools and summarised graphically. In this way we made a significant contribution to our customer's assessment report.
In the course of this contract we contributed our expertise in the performance testing of data links.
At the same time we obtained an in-depth knowledge of the properties of the data links themselves.
