Composite 1×6 Video Distribution Amplifier
VDA106
-
Video Distribution Amplifiers (sometimes called a video splitter – not to be confused with a video split screen controller such as our PXD510E split screen controller) are typically used for connecting a camera or other video source to several monitors that do not have “looping” inputs. In this situation, each monitor has a permanent 75 ohm termination. With two non-looping monitors connected together, the line would be double loaded and result in a dim picture on each monitor. Using a Video Distribution Amplifier will solve this problem by driving each monitor individually at 100%.

Low Voltage DC / Battery Powered HV Amplifiers
WMA-01 And WMA-01LF
-
The Falco Systems WMA-01 is a high voltage amplifier that runs from an 24 - 30V DC power supply and can be battery powered if required, e.g. for use in a Faraday cage. Its internal high voltage generator is inductor-free and hence does not spread magnetic interference in sensitive experimental setups. The output noise is impressively low at 3mVrms. For extremely low noise applications where bandwidth is not an issue, a dedicated WMA-01LF version is available that contains an output low pass filter capacitor which reduces the bandwidth to 50Hz, but makes the noise drop to below 0.1mVrms. This bandwidth-limited amplifier is ideal for MEMS or piezo positioning with manual voltage adjustment.

Low-noise High-voltage Amplifier For Tube-scanners -
HV200/5
-
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.
