Product Overview
The MS4110 phase comparator is an instrument based on the dual-mixing time difference measurement principle, utilizing digital technology to perform frequency measurement. The device consists of a main unit and monitoring and data processing software. Its basic function is to analyze the relative frequency deviation, phase difference, and frequency stability of the measured frequency. It can accept an external signal source as a reference to perform phase comparison and measurement between multiple frequency signals. The accompanying software provides device monitoring, configuration management, file generation, and storage. The MS4110 phase comparator is housed in a 2U rack-mountable chassis and houses a lighting board, frequency mixer module, time difference measurement module, frequency division module, and power supply module.
Basic Functions:
Accepts eight external measurement signal inputs;
Accepts one external 10MHz reference input for frequency source calibration;
Provides network and serial port monitoring capabilities;
Features user-friendly host software for real-time acquisition, processing, and storage of measurement results.
