Femto GmbH has introduced the HLVA-100 logarithmic wideband voltage amplifier. This Femto device has a dynamic range of up to 80 dB. With a DC coupled input and a rise and fall time of 5 ns, the HLVA-100 is suitable for the measurement of fast and high dynamic pulses. The input voltage noise is low (2 nV/Hz1/2). Features include Adjustable Input Range, trimpots (for baseline adjustment when coupled with instruments such as A/D converters or oscilloscopes) and an integrated sample amd hold circuit for automated baseline correction of the amplifier. The HLVA-100 is switchable at the amplifier or remotely (using the 25 pin D-Sub connector). The amplifier is laid out in a compact EMI shielded aluminum package with 50?terminated BNC connectors on the input and output. Typical applications include signal compression, time-resolved pulse and transient measurements, mass spectroscopy, particle detection and LIDAR systems.
