The 178 Linear IC Test Fixture is a plug-in device for the use with 577 curve tracer. Using a plug-in card system, it measures parameters of operation amplifiers, comparator, differential amplifiers and regulator. It contains a sweep generator, positive and negative supplies and switching mechanics and circuits. The DUT is part of a negative feedback loop, enabling closed-loop measurement of input-referred offset, power supply rejection, common-mode rejection, gain, input bias current, input offset current, supply current, all as a function of input range. The load and source resistances can be chosen, as well as the sweep frequency. All in all, this is a unique and very versatile instrument.
