50 Ω Bipolar or 1 MΩ FET Input Stage

主要特点：
Bandwidth 
For optimum signal-to-noise performance choose an amplifier with sufficient bandwidth corresponding to the required signal bandwidth. However, keep in mind that unnecessary high bandwidth introduces more wideband noise. Therefore, FEMTO offers HVA Voltage Amplifiers with three different upper cut-off frequencies to match individual measurement requirements. And as with all FEMTO Adjustable-Gain Amplifiers the bandwidth remains constant when switching between the different gain settings which is very important for measuring fast signals and pulses. 
True DC-Coupling with Zero Output Offset 
True DC-Coupling is extremely important for accurate pulse amplification and analysis especially when different pulse lengths occur like in digital codes or transients with micro- to millisecond duration. If the amplifier is AC coupled or has a large output offset to be de-coupled by the AC setting of the oscilloscope there will be significant undershoots and baseline shifts in the measurements. Therefore, all HVA Amplifiers offer a true DC coupling and an adjustable output offset control even with the 500 MHz model. 
Very Low Input Noise 
Low input noise is very important for a good signal-to-noise ratio, especially when amplifying small signals. All HVA Amplifiers are optimized for minimum input noise reaching excellent values as low as 0.9 nV/√Hz.
