- low-noise high-voltage amplifier for tube-scanners -

The HV200/5 is a high-precision HV-amplifier designed for the control of tube scanners. It takes three input voltages In X, In Y and In Z (-10 V to + 10 V), amplifies them separately (input gain switches: x1, x2, x5, x10, x20) and adds an offset voltage between -10 V and +10 V. In a 2nd stage, the signal is amplified by a factor of 20. This enables its use as HV amplifier in scanning image acquisition applications, such as STM or AFM, with the capability to shift the scan range in high resolution imaging.
