Second, the main features
■ hardware using switching power supply and linear power amplifier combination configuration, which improves the reliability, but also to ensure that the current and voltage accuracy and smooth waveform, the weight is greatly reduced.
■ Standard 12-channel D / A + 6u + 61 flexible combination of 12 (6 current, 6 voltage) analog output at the same time any.
■ Built-in computer integrated device, 10.4 true color LCD large screen display, running WindowsXp operating system; and embedded GPS global satellite receiver can be synchronized on both sides of the test, for debugging fiber pilot protection has a high advantage.
■ The total power supply is incorrectly connected to 380VAC to protect the equipment and alarm.
■ Software features
