AB  -     Measurement of Op-Amp Parameters Using Vector Signal    Analyzers in Undergraduate Linear Circuits LaboratoryAbstractMeasurements of op-amp circuit parameters such as frequency response (bothopen-loop and closed loop) or output impedance (as a function of frequency, overa reasonably broad range of frequencies) can be tedious and very challenging forundergraduate students to accomplish using signal generators and oscilloscopes.In fact, measurements of total harmonic distortion (measure of op-amp linearity),with and without resistive load, are almost impossible to make in the time domainwith conventional oscilloscopes. Of greater concern, however, is that time-domain methods for measuring frequency domain characteristics of an op-amp donot present a “real-time” visualization for students, and can even mask importantoperational limitations (such as op-amp slew-rate nonlinearities for higherfrequency sinusoidal inputs).Here we present some of the successful measurement methodologies our facultyand students have used at the U.S. Coast Guard Academy in a junior-level LinearCircuits laboratory. As part of this lab, students use the Agilent 35670 DynamicSignal Analyzer (DSA) to measure the open-loop and closed-loop frequencyresponses, and output resistance, of an inverting amplifier op-amp (µA741)circuit. They also compare the Total Harmonic Distortion (THD) at the outputand inverting input, for unloaded and resistive load conditions. Frequencyresponse measurements are compared with theoretical expectations (fromMatlabTM) and with MultiSimTM AC analysis simulations, thereby solidifying thefrequency domain presentation of real-world op-amp characteristics.Finally, we present typical measurement results, along with informal studentfeedback that suggests to us that the “real-time” nature of a DSA frequencydomain presentation (that looks almost exactly like MatlabTM and MultiSimTMpredictions) really does reinforce student learning.
