RTCA/DO-260 TEST COMMANDS
These commands allow the definition of different RTCA/DO-260 tests. The Unit has implemented the
following type of tests: Normal Test, Bit Failures Special Test, Altered Preamble Special Test,
Overlapping Pulse Special Test, Confidence Test and Preamble Validation Test.
The Normal Test is a test that allows the definition of one type of message (Mode S or Mode A/Mode C
or none) for each generator available for the test. The generator available for the test depends on the
power mode (Low Power or High Po wer). In Low Power Mode, all generators are available. In High
Power Mode, only generators GENA, GENC and GENE are available.
For the special tests (Bit Failures, Altered Preamble, Overlapping Pulse, Confidence Test and Preamble
Validation) only two generators are available (GENA and GENC). The generator GENA is used to define
the reference (Mode S message) and generator GENC is used to define the special test.
