The FEMTO HLVA-100 offers a wide dynamic range of up to 80 dB. With a DC coupled input and a rise and fall time of just 5 ns the HLVA-100 is the ideal tool for the measurement of fast and high dynamic pulses. The input voltage noise is extremely low with just 2 nV/√Hz. The logarithmic gain curve offers high gain for small input signals and relatively low gain for high input signals. Therefore the HLVA-100 is the ideal amplifier for signals with high dynamic range and applications in which a signal compression is desired.
The HLVA-100 provides 3 possibilities of an input offset voltage correction (baseline correction). All three methods cancel both temperature drift dependent offset and small source voltage offset:
