We have developed the power analyzer PZ4000 for power measurement and waveform observation. This new concept power analyzer features a trend display for the measurement of transient power and a span measurement function. Despite having a wide bandwidth of DC-2 MHz which facilitates the accurate measurement of switching control waveforms or fluctuating power and a fast sampling rate of 5 MS/s, it is capable of precise measurements at an accuracy of (±0.1% of reading +0.025% of range). It can analyze wide band distorted waveforms with a maximum harmonic analysis order of 500 th . This paper contains an overview of the instrument.
