The PTC-ACSES Analyzer option provides a method to verify the operation of ACSES Positive Train Control (PTC) systems. PTC-ACSES is an integrated communication and information system for controlling train movements. Option 731 includes the ability to display constellation, spectrum, and eye-diagram graphs. In addition, a summary table displays numeric values of received power or burst power, PEP (Peak Envelope Power), frequency error, EVM (Error Vector Magnitude), BER (Bit Error Rate), and phase and magnitude error.
BER is a comparison against standard PTC test patterns and is calculated based on forward error correction (FEC).
The LMR Master will analyze input signal strengths from +33 dBm (2.0 watts) down to levels approaching the sensitivity of PTC radios, automatically adjusting the input sensitivity based on input levels.
