Intersoft Electronics RFA641 - Key Specifications; General Specifications; Target Types; Scenario

Radar Field Analyser - RFA641 Edition Date: 28-Feb-18
Different test scenarios can be generated, (according to RTCA DO260/260A ) with different levels of
interference signal load, level, power, position in squitter reply, etc… In each of these cases, a different
detection level is to be expected.
