The **ATG-2123-R** is a high-voltage power signal generator (often categorized as a high-voltage amplifier) manufactured by Aigtek. It is designed to amplify sine waves, square waves, triangle waves, and arbitrary waveforms to high-voltage outputs. --- ### ## Technical Specifications Below is a breakdown of the core electronic parameters of the ATG-2123-R: | Parameter | Specification | | :--- | :--- | | **Output Voltage** | 160Vp-p (±80Vp) | | **Output Current** | 500mA (Peak) | | **Frequency Range** | DC to 450kHz | | **Output Power** | 40W | | **Output Impedance** | Adjustable (Low/High resistance modes) | | **Waveform Types** | Sine, Square, Triangle, Pulse, Sawtooth, DC, Arbitrary | --- ### ### Key Electronic Features #### 1. Signal Amplification & Generation Unlike a standard function generator that outputs low-voltage signals (usually <20V), the ATG-2123-R integrates a **high-voltage power amplifier stage**. It can take an internal digital signal or an external analog input and scale it up to 160Vp-p while maintaining signal integrity. #### 2. LCD Display & Interface The device utilizes a digital control interface that allows users to adjust parameters such as: - **Amplitude:** Precise control over the voltage swing. - **Offset:** Shifting the waveform vertically relative to zero. - **Phase:** Adjusting the start point of the wave. #### 3. Protection Circuitry To protect the internal electronic components and the connected Load (DUT), the device includes: - **Overcurrent Protection:** Shuts down if the current exceeds 500mA. - **Overheating Protection:** Internal thermal sensors monitor the power stage. - **Short Circuit Protection:** Prevents damage if the output terminals are bridged. #### 4. Dual Channel Functionality The "2" in the 2000 series often denotes dual-channel capabilities, allowing the user to output two different high-voltage signals simultaneously with synchronized or independent phases. --- ### ### Common Applications Due to its ability to drive capacitive and inductive loads at high frequencies, it is used for: - **Piezoelectric Transducer Driving:** Requires high voltage and specific frequencies. - **MEMS Testing:** Characterizing micro-electromechanical systems. - **Ultrasonic Research:** Driving ultrasonic sensors. - **Cell Electroporation:** Delivering precise pulses for biological research.
