Introduction:
1.Signal generator
The "YELLOW COLOR" marked frame is included in signal generator box. Signal
generator is equipped with DDS waveform technology (digital frequency
modulation, amplitude modulation and phase modulation). Embedded MCU is
the brain of signal generator, also it is the brain of testbench, signal generator
generate high stability sine waveform which is send to voltage amplifier and
current amplifier.
2. Power amplifier
Power amplifier features stability and reliability with the PWM amplify
technology and well-designed protection when output voltage shortcut and
output current circuit open.
