Voltage & current preamplifier

Low noise preamplifiers are used to amplify a signal at an acceptable and measurable level; but in addition to this first function, they can be used for many other functions such as adapting the impedance, increasing the sensitivity of your oscilloscopes… The analog low-noise preamplifiers proposed by HTDS (manufactured by Signal Recovery – ex EG & G) are specially designed for the most demanding measurements. Our wide range of preamplifiers (wide-band, differential, high and low impedance…) will respond optimally to your needs for amplification, impedance matching and low signal processing.

Any advice ? any question ?
