HUATEK H20000 Series - H22203 Amplifier

HUATEK H20000 Series - H22203 Amplifier

1. Overview

The HUATEK H20000 Series - H22203 Amplifier redefines the desktop high-voltage signal amplifier (four-quadrant power supply). Designed with modern instrumentation principles, it features a compact form factor with a height of just 1U and a volume comparable to a stack of A4 paper. The chassis is constructed entirely from aluminum alloy and utilizes DC power supply. It incorporates digitally controlled gain, digitally controlled offset, short-circuit protection, and other functions.

6. Verifying Amplifier Performance

The most intuitive and straightforward method to verify the voltage amplifier's performance is to use an arbitrary waveform generator to produce a voltage signal, input it into the voltage amplifier, and use an oscilloscope to monitor the amplifier's output voltage and waveform.

Key considerations during this process:

1. The input impedance of the H20000 series voltage amplifiers is      10 kΩ. Set the arbitrary waveform generator to "High-Z mode".
2. The output impedance of the H20000 series is 50 Ω. Set the      oscilloscope to "50 Ω mode".
3. Set the oscilloscope's display measurement to match the      parameter set on the arbitrary waveform generator. For example, if the      generator is set to "Voltage Peak-to-Peak", the oscilloscope      should also display "Voltage Peak-to-Peak". Using different      measurements (e.g., RMS or peak voltage) will not yield accurate      verification results.
4. Ensure the amplifier's output voltage does not exceed the      oscilloscope's input range. If it does, use an attenuating probe and set      the oscilloscope's probe attenuation factor accordingly.
5. SAFETY WARNING: The output      voltage of the H20000 series high-voltage amplifiers is potentially      lethal. Always implement appropriate safety measures and strictly adhere      to operating procedures. Do NOT make any connections to the high-voltage      output terminals while the unit is powered on. All connections to the load      must be made with the device powered off.
