GDM-16 Fault Recording & Generator Characteristic Test Set
General Information
GDM-16 Generator Characteristic Comprehensive Test System is based on the industrial portable machine structure, with high-performance DSP, high-precision ADC chip, embedded operating system as hardware and software architecture, which integrates data collection, processing, transmission, storage, analysis and other functions as one portable device.
DSP acquisition chip is used for data acquisition and calculation, so as to realize full digital analog signal filtering. Flexible and diverse sampling frequencies from 10K/s, 20K/s, 50K/s, 100k/s can be selected by users, and can be used for waveform recording and analysis of transient electrical signals.
Using advanced industrial control kernel, combined with embedded operating system, users can easily perform data storage, backup, analysis, export and other operations.
The generator characteristic comprehensive test system is a smart instrument that integrates functions such as fault recording and generator characteristic test. It is favored by the majority of users for its small size, strong function, wide application range, flexible configuration and many other advantages.
