1、DESCRIPTION The Model 30A Series low-pass, elliptical filter/voltage gain amplifier is one of many plug-in filter cards used in the Models 3905B/3905C/3916B/3916CProgrammableFilterSystems chassis. FILTER?FEATURES As an elliptical filter, the Model 30A Series has a tunable cutoff frequency range from

2、 1Hz to 99kHz, a roll-off rate of 115dB/octave and a minimum stopband attenuation of 80dB. Pass-?band?ripple?is?typically?0.22dB. The30Aprovideseitherasingle-endedordifferentialinputwitha common mode rejection of 60dB. Input gains up to 40dB in 10dB steps and output gains to 20dB are also provided.

3、The 30A will accept input signals of 10V peak at 0dB gain and has selectable ac or dc coupling. Overload detectors are standard and assist the user in detecting excessive input signals or incorrect gain?settings.
