The TETRA Analyzer option provides a method to verify the operation of TETRA repeater transmitters. Option 581 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, error vector magnitude (EVM), IQ imbalance, phase and magnitude errors, and symbol rate error of the input signal. The analyzer also reports the base station extended color code (BS ECC), mobile color code (Mobile CC), mobile network code (Mobile NC), base color code (Base CC), location area code (LAC), and mobile station maximum transmit power (MS Max TX Pwr) permitted on a channel from the TETRA transmitter.

The LMR Master TETRA Analyzer and TETRA 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 TETRA Analyzer mode.

The LMR Master will analyze input signal strengths from +33 dBm (2.0 watts) down to levels approaching the sensitivity of TETRA radios, automatically adjusting the input sensitivity based on input levels.
