BAND-PASS/BAND-REJECT OPERATION:With the Model 3382 and 3384 models, the user can simply connect two channels in series to achieve band-pass operation or two summed in parallel for band-reject operation. Each channel of the 3380 Series is a selectable low-pass or high-pass, 8-pole filter providing an input gain to 50dB, and an output gain to 20dB selectable in 0.1dB steps. The 3380 Series will accept input signals to ±10V peak at 0dB gain and has selectable ac or dc coupling. Memory is available for storing a set-up of the instrument which can be recalled with a simple command. Attenuation: 48dB/Octave Filter Mode: Selectable Low-Pass and High-Pass Response: Selectable Butterworth and Bessel Input: Differential and Single-Ended Input Gain: 0dB to 50dB in 10dB steps Output Gain: 0dB to 20dB in 0.1dB steps Battery Option
