Where Accuracy Meets Versatility

 2013 Product of the Year AwardFeaturing Spiral Shunt™ technology, the new Tektronix PA4000 Power Analyzer delivers consistently accurate measurements, even with challenging power waveforms. While most power analyzers rely on zero-crossing point to detect and track fundamental frequency, the PA4000 Power Analyzer uses a unique method to lock onto signals, no matter how complex. Add in wide current and voltage input ranges, built-in test modes and standard PC interfaces, and you have a power analyzer that’s as versatile as it is accurate.
