Introduction
The P25 Phase 2 Analyzer option provides a method to verify the operation of APCO Project 25 Phase 2 (P25p2) and Linear Simulcast Modulation (LSM) tower, mobile, and portable radio transmitters. Option 521 includes the ability to display linear constellation, spectrum, histogram, power profile, and eye diagram graphs. In addition, summary graphs display demodulation, active and backup control channel, band plan, and adjacent site information.
The LMR Master will analyze input signal strengths from +33 dBm (2.0 watts) down to levels approaching the sensitivity of P25p2 radios, automatically adjusting the input sensitivity based on input levels.
