Tektronix ADA400A Differential Preamplifier

The ADA400A Differential Preamplifier allows direct oscilloscope measurements of very low amplitude voltages and signals which are not ground referenced. The high impedance of both inputs eliminates the need to add additional ground points in the DUT, thereby avoiding circulating currents which disturb the measurement or the circuit.

Key performance specifications

    10 μV/div sensitivity
    Typically 100 dB CMRR DC to 10 kHz
