High-speed amplifiers

HSA series amplifiers from Femto GmbH for time-resolved measurements can be used with photomultipliers and avalanche or PIN photodiodes. HSA-X amplifiers have an integrated bias coil, a bandwidth up to 2 GHz, a gain up to 60 dB, and low noise of 1.9 dB. HSA-Y amplifiers have the same features, plus a dc monitor for detector control and a second equivalent signal output for triggering or signal control.
