I. Technical Description
The main control board is DSP + FPGA architecture, 16 bit DAC output, generates high - density sine wave 2000 points each circle to fundamental wave, which greatly improve the wave quality and the accuracy of the test instrument.

Classic Windows XP operating interface, friendly man-machine interface, easy and fast to operate; High-performance embedded industrial control computer and 8.4 inch resolution of 800 × 600 TFT true color display which provides rich visual information, includes the current working condition and all kinds of help information.

The software with self-calibrating function, which avoid to calibrate accuracy by adjusting relays after open the case, greatly improve the stability of the accuracy.
II. Function and features

Classic Windows user interface, friendly interface, easy operation;
Built-in PC104 series of high performance industrial computer and 8.4 "large screen high-resolution color TFT LCD display. It can provide a rich visual information, including working conditions of the equipment, the next step tips and all kinds of help information;
Equipped with ultra-thin 101 standard keyboard and optical mouse, you can operate it the same way as an common PC;
Equipped with an external USB interface for easy data access and software maintenance;
Complete all projects without other external devices with automatic display and record of test data, and completion of drawing of vector and characteristic curves;
The wave is with high precision and good linearity by high-performance 16-bit D / A converter; besides, it has a good transient response and amplitude-frequency characteristics. In the entire measurement range, it can guarantee precision waveform.
Unique algorithm makes the waveform accurate and guarantees that the signal is the pure sine wave.
Direct output AC voltage, AC current, DC voltage, DC current, variable phase, and variable frequency;
Except traditional Ua, Ub, Uc, Ia, Ib, Ic, there is also a fourth output voltages Ux. Ux can be used for a variety of functions, such as for the output of various 3U0, the voltage of output line during line protection tests and so on;
110V / 220V auxiliary adjustable DC power supply, maximum output current up to 1A, voltage can be adjusted within 80% to 100%, and can be used as DC operating power supply of device and circuit and 80% of test voltage;
It is with 8 inputs and 4 open into the air out of the amount of output contacts. The input interface can automatically adapt to both the passive (air contact) and the active, and can automatically adapt to the active input of the polarity. It can work normally within the input voltage range of ±250V.
GPS synchronization trigger error is less than 50μS；
It can complete the complex verification, scan and test all kinds of protective value, and playback faults. It also can do real-time data-saving, vector display, reports printing, etc. ;
Well-designed chassis structure, small size, good heat dissipation. With comprehensive and reliable protection, fault diagnosis and automatic locking function;
