Abstract
A radio interference detection and screening system for performs on-locomotive testing of Locomotive Control Unit (LCU) radios. To eliminate bit errors during LCU sensitivity testing (also known as Bit Error Rate (BER) testing), the system detects interfering transmission signals which may cause bit errors in the transmission of test data, and suspends the LCU sensitivity performance testing during periods of detected external transmissions. Once the interfering transmissions are no longer detected by the system, the LCU then resumes the LCU sensitivity performance testing.
