The DMR Analyzer option provides a method to verify the operation of Digital Mobile Radio (DMR) compliant equipment. DMR is an open digital radio standard specified in the European Telecommunications Standards Institute (ETSI) Standards TS 102 361. Option 591 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), bit error rate (BER), symbol deviation, Color Code (CC), and symbol rate error of the input signal. BER comparisons can be made to the 1031 Hz Standard Tone or the Standard Transmitter Test (O.153) pattern, regular voice traffic using a proprietary algorithm.
