About this file
This document contains minimum specifications for an LMR (Land Mobile Radio) Service Monitor, detailing comprehensive technical requirements for a sophisticated electronic measurement device. The specifications outline a high-performance instrument with a frequency range of 100 kHz to 3 GHz, exceptional accuracy (≤ 0.02 ppm from 0°C to 50°C), and advanced capabilities including a built-in tracking generator, spectrum analyzer functionality, and support for multiple modulation types (AM, FM, PM). Key technical parameters include spectral purity specifications, RF port output ranges, receiver sensitivity, and operational characteristics such as a wide resolution bandwidth (25 Hz to 6 MHz), sweep time range (0.4 ms to 1000 s), and a robust operating temperature range of 0°C to 50°C, all while maintaining a lightweight design under 15 lbs.
