Technical Features
1. Uses easy-to-use Windows XP operating system, friendly human-machine interface, simple and quick operation. To facilitate user use, many keyboard shortcuts are defined, making operation "one-key to position".
2. High-performance embedded industrial control computer and large-screen high-resolution color TFT LCD display provide rich and intuitive information, including the current working status of the device, next-step work prompts, and various help information.
3. Equipped with ultra-thin industrial keyboard and touch mouse, all operations can be completed via keyboard or mouse just like operating a regular PC.
4. Equipped with external USB interface for convenient data storage and software maintenance.
5. Can complete all project tests without external devices, automatically display and record test data, and draw vector diagrams and characteristic curves.
6. Uses high-performance D/A converter, producing waveforms with high precision, good linearity, and good transient response and amplitude-frequency characteristics. Waveform accuracy and other indicators are guaranteed throughout the entire measurement range.
7. Can directly output AC voltage, AC current, DC voltage, DC current, with variable amplitude, phase angle, and frequency.
