HUATEK H20808 800V High-Voltage Amplifier - New Product Recommendation

HUATEK H20808 800V High-Voltage Amplifier - New Product Recommendation 

1. Overview

The HUATEK H20000 Series - H20808 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 functions such as digitally controlled gain, digitally controlled offset, and short-circuit protection.

6. Verifying Amplifier Performance

A straightforward way to verify the voltage amplifier's performance is to use an arbitrary waveform generator to produce a voltage signal, input it into the amplifier, and monitor the output voltage and waveform using an oscilloscope.

Key considerations:

1. The input impedance of the H20000 series amplifiers is 10 kΩ.      Set the arbitrary waveform generator to "High-Z mode".
2. The output impedance is 50 Ω. Set the oscilloscope to "50      Ω mode".
3. Match the oscilloscope's display measurement to the generator's      setting. For example, if using "Voltage Peak-to-Peak" on the      generator, use the same on the oscilloscope. Using mismatched measurements      (e.g., RMS vs. peak) will not yield accurate results.
4. Ensure the amplifier's output does not exceed the      oscilloscope's input range. If it does, use an appropriate attenuating      probe and set the oscilloscope's 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.
