Pulsed IV analysis allows the develop-ment of more accu-rate nonlinear models for RF and microwave device operation. An analysis of pulsed IV waveforms allows better exploitation of measurement capabilities to produce accurate results. Static and dynamic IV measurement waveforms pro-duced by a commercially available pulsed IV analyzer are examined. Because transistors can become unstable during any type of IV measurement, the use of bias tees allows a fre-quency-dependent impedance to be present-ed. However, it is shown that care must be used when using bias tees in pulsed IV mea-surement to choose a bias tee with an inductor time constant significantly higher than the pulsing frequency but significantly lower than the frequency at which oscillations develop.
