voltagepowercurrent

Overview
The ATA-2082B is an ideal dual-channel high-voltage amplifier capable of amplifying both AC and DC signals. With a maximum output of 1600Vp‑p (±800V), it can drive high-voltage loads. The digitally adjustable voltage gain allows precise tuning, with one-click saving of common settings for convenient and user-friendly operation. It is compatible with mainstream signal generators, delivering excellent signal amplification.

Input
The input uses a BNC interface with selectable impedance of 50Ω or 100kΩ, perfectly matching both high and low impedance signal sources.

Output
The output interface is a 4mm banana socket, with selectable output modes. In differential mode, the maximum output voltage is 1600Vp‑p (±800Vp). In single-ended mode, the maximum output voltage is 800Vp‑p (±400Vp). The maximum output current is 65mAp.

LCD Displays
The LCD panel display dynamically shows device status and parameters, offering a clear and intuitive interface.

Voltage Gain
The voltage gain is digitally adjustable from 0 to 200×, with both coarse adjustment (1 step) and fine adjustment (0.1 step) available. Combined with the gain display on the LCD panel, the voltage can be quickly and precisely adjusted as needed.

Monitor

• 10mV/V Monitor: This port voltage is 1/100 of the output port voltage. The monitoring port uses a BNC connector and can be directly connected to an oscilloscope for real-time monitoring of the output voltage.
• 20V/A Monitor: The monitoring port voltage is 20 times the output current. The monitoring port uses a BNC connector and can be directly connected to an oscilloscope for real-time monitoring of the output current.
• In differential mode, the voltage monitoring ratio is 5mV/V, and the current monitoring ratio is 20V/A.
