Introduction
The dPMR Analyzer option provides a method to verify the operation of dPMR tower, mobile, and portable radio transmitters. Option 573 includes the ability to display constellation, spectrum, histogram, and eye diagram graphs. In addition, a summary graph displays numeric values of received power, frequency error, modulation fidelity (Mod Fid), symbol deviation, and symbol rate error of the input signal.
The LMR Master dPMR Analyzer and dPMR Coverage Mapping options are intended for use on over‑the‑air (OTA) signals. The LMR Master signal generator outputs CW, AM and FM signals while in the dPMR Analyzer mode.
The LMR Master will analyze input signal strengths from +33 dBm (2.0 watts) down to levels approaching the sensitivity of dPMR radios, automatically adjusting the input sensitivity based on input levels.
