Tektronix Inc. has extended its family of precision power analyzers with the roll out of the PA1000 single-phase power analyzer. The device offers a patent pending Spiral Shunt design and claims to provide engineers designing and testing power supplies, consumer electronics and other electrical products with accurate power measurements in the shortest possible time.

The analyzer features a color graphical display, one-button application modes and intuitive menu system enable optimum instrument set up in seconds. It also flaunts the PWRVIEW PC software that includes comprehensive reporting features such as a full compliance IEC62301 standby power certificate.


The PA1000 single-phase power analyzer complements the PA4000 series of precision three-phase power analyzers, as well as Tektronix oscilloscopes and probes for circuit analysis, giving engineers end-to-end solutions for optimizing and debugging power electronics designs.

The PA1000 promises to offer the best overall performance in its class, with 0.05 percent basic accuracy and 1MHz measurement bandwidth. Two internal current shunts are included on each PA1000, one for current measurements up to 1A, for precise low-current measurements, and another for current measurements up to 20A. The 1A shunt is particularly useful for maintaining measurements resolution and accuracy on demanding low-current signals common to standby power testing.

A full-color graphics display, unusual in this instrument class, makes setup and other tasks easy and intuitive, with one-button access to measurement results, power waveforms, harmonic bar graphs and menus. Application-specific test modes for standby current, lamp ballast testing and energy integration help to simplify optimization of instrument settings, saving engineers time and reducing mistakes. PWRVIEW PC software further simplifies testing with one-click test automation for compliance-test applications.

The PA1000 also offers LAN, USB and GPIB interfaces, harmonic analysis, and PC software that cost extra on many analyzers. A five-year warranty and Tektronix worldwide support and service add to the value proposition.

Based on recent field and metrology analysis, Tektronix has released improved accuracy specifications for the PA4000 power analyzer and extended the standard warranty to five years from the previous three years. The accuracy specifications apply to RMS voltage, RMS current and power. For instance RMS voltage accuracy was rated at ±0.04 percent and has now been improved to a rating of ±0.01 percent.

The PA1000 will be available worldwide starting in December 2013. Prices start at $2790.
