Feature:
High-Performance Industrial Control Computer
High performance Industrial control computer is adopted as the controlling computer, through which you can run the windows operating system directly.
Digital Signal Processor Microcomputer
High-speed digital controlling processor is adopted as the output core of the tester. 32 bit double precision arithmetic is employed in the software, through which arbitrary high-accuracy waveforms of each phase can be produced.
D/A Conversion and Low-Pass Filtering
High precision D/A converter is employed for ensuring the precision and linearity of current and voltage in the whole range.
Voltage and Current Amplifier
For phase current and voltage, we persist in adopting high performance linear amplifier output mode in order to make the current and voltage source to directly output all kinds of waveforms from the DC waveform to the waveforms including all kinds of frequency components
