The Tektronix ADA400A Differential Preamplifier is engineered for precision measurements of low amplitude, non-ground-referenced signals directly via oscilloscope. It features high input impedance to prevent measurement disturbance and offers selectable bandwidth limiting for reduced noise from digital or power supply sources.
It supports high gain with excellent common mode rejection, making it ideal for noisy environments. The offset adjustment and infinite impedance mode enhance flexibility and accuracy for sensitive applications.
