Tektronix precision tool analyses GaN and SiC power

New semiconductor technologies such as GaN (gallium nitride) and SiC (silicon carbide) are emerging to meet the greater demands of today. To meet these requirements, new test and measurement tools such as the PA1000 are needed to keep pace
Tektronix has expanded its family of precision power analysers with the introduction of the PA1000 single-phase power analyser.

Featuring a patent pending Spiral Shunt design, the PA1000 provides engineers designing and testing power supplies, consumer electronics and other electrical products with accurate power measurements in the shortest possible time.

Features such as a colour graphical display, one-button application modes and intuitive menu system enable optimum instrument set up in seconds, and the powerful PWRVIEW PC software includes comprehensive reporting features such as a full compliance IEC62301 standby power certificate.

Engineers developing power supplies for single-phase electronics face new demands for greater energy efficiency and lower line pollution, along with a growing array of government regulations and commercial demands to reduce energy consumption.

As new semiconductor technologies such as GaN and SiC emerge to meet these demands, new test and measurement tools such as the PA1000 are required to keep pace.

The new PA1000 single-phase power analyser complements the PA4000 series of precision three-phase power analysers introduced earlier this year, as well as Tektronix oscilloscopes and probes for circuit analysis, giving engineers end-to-end solutions for optimising and debugging power electronics designs.

"Power is one of the most dynamic segments in electronics today given the intense interest on the part of consumers, business and government to reduce overall energy consumption. Improving battery life is another key driver," says Curt Willener, general manager, Power Analyser Product Line, Tektronix. "To help our customers meets these demands, Tektronix continues to step up with the precision instruments they need such as the PA1000 and PA4000 power analysers with a compelling combination of industry leading performance, value and usability."

Accuracy and Value

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

A full-colour 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 optimisation 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 offers standard features including LAN, USB and GPIB interfaces, harmonic analysis, and PC software that cost extra on many analysers. A five-year warranty and Tektronix worldwide support and service add to the value proposition.

PA4000 Accuracy Specifications, Warranty Upgrades

Based on recent field and metrology analysis, Tektronix has released improved accuracy specifications for the PA4000 power analyser and extended the standard warranty to five years from the previous three years. The new 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.

Pricing & Availability

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