PA4000 Power Analyzer

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.

Models in the PA4000 Power Analyzer Series: 



Uncompromised Measurement Accuracy Have confidence in your measurements, even if your power is far from sinusoidal.
Dual Spiral Shunt Current Shunts Maximize stability over the entire current, frequency, and temperature range. Every input channel includes both a 1 A and a 30 A shunt for measuring from µW to kW with one instrument.
Full Suite of Power Measurements Covers your measurement requirements from RMS current and voltage to harmonics up to the 100th harmonic.
High Crest Factor Tolerance Measure accurately with current crest factors up to 10.
Fast Autoranging for Voltage and Current Inputs Responds quickly to changes in input levels, ensuring that you get good data even under variable conditions.
Application-specific Test Modes Built-in PWM motor mode, lighting ballast mode, standby current mode, and integrator mode, let you quickly configure for specific applications.
USB, LAN and RS-232 interfaces come standard Every instrument comes with common PC interfaces, and a USB flash drive port, making it easy to get your data.  PWRVIEW™ software is included with the instrument, and GPIB is available as an option.
