  • Notes
  • The 7A13 is a differential comparator plug-in amplifier for either 7704 or 7504 mainframes.

    As a conventional amplifier the 7A13 has excellent, and constant, bandwidth over the 1 mV/div to 5 V/div deflection factor range. The bandwidth is selectable at FULL (100MHz in the 7704, 75MHz in the 7504) or 5 MHz for best displayed noise conditions during low frequency applications. The + or - INPUTS allow normal or inverted displays.
    As a differential amplifier the 7A13 maintains its conventional features and provides a balanced (+ and —) input for applications requiring rejection of a common-mode signal. The CMRR is 20.000:1 from DC to 100 kHz, derating to 250:1 at 20 MHz. The unit can reject up to 10V of common-mode signal at a deflection factor setting of 1 mV/div, increasing to 100V rejection potential at 10 mV/div on Vc pulled) and 500 V at 0.1 V/div.
    The 7A13 utilizes its differential capabilities but provides an accurate (0.1%) positive or negative internal offsetting voltage covering the common-mode signal range of the unit. A signal of up to +-10  V may be applied to an input (+ or —) at a deflection factor setting of 1 mV/div end, with an opposing Vc (offset voltage), viewed in 10,000 segments of 1 mV. The offset voltage is also available as an output for external monitoring.
