High-Voltage Amplifiers
Nanonis offers a low noise, high-voltage amplifier specifically designed for nanopositioning applications, such as piezotube scanner for either room temperature or low-temperature applications. With a noise level of only 80μVrms in a bandwidth of 2kHz, the HVA4 offers the lowest noise on the market in scanning probe applications.

4 Inputs / 6 Outputs |
 |
 |
 |
 |
 |

|
 |
With 4 inputs and 6 outputs, the HVA4 can handle any type of piezotube scanner. X/Y, Z and AUX have independent turn-on switches with LED indicators. The auxiliary channel can for instance be used for high-voltage bias, interferometer regulation or to drive a simple coarse motor (with function generator module). |

Selectable Gains and Bandwidth |
 |
 |
 |
 |
 |

|
 |
Each axis has 4 selectable gains from 3 predefined set depending on the application: (1, 3, 7, 14); (1, 4, 10, 22) or (1, 4, 15, 40). The actual gain is indicated with an LED on the front panel and digitally read-back by the software for a consistent use. The Z- and AUX- channels have a inverter switch to change output polarity. |
