Multi-phase power analyser with 1 MHz b/w & milliWatt standby measurements

March 23, 2016 // By Graham Prophet
Tektronix’ PA3000 is a 1- to 4-channel AC/DC power analyser for testing single- and multi-phase, high efficiency AC-DC and DC-AC power supply designs. The PA3000 is, Tek says, the first multi-channel power analyser with 10 mW standby power measurement capabilities and a 1 MHz bandwidth, with mid-range pricing.

Meeting requirements such as Level VI efficiency standards and IEC 62301 standby power means, Tek proposes, that power analysers should be standard on every engineer's bench. "In looking at the changing power test landscape, it's clear that a versatile, cost-effective power analysis solution is a critical need across the board," said Mike Flaherty, general manager, Power Analyzer product line, Tektronix. "The PA3000 delivers a unique combination of milliwatt-level measurements for standby power testing to the latest standards, and more than enough bandwidth to support applications like wireless charging, LED lighting, and other applications where high fundamental frequencies are involved. We also made it easy to use with a colour graphical display so users can quickly see harmonics, crest factor and noise."


Suitable for a broad range of R&D and validation applications, the PA3000 supports testing to Level VI efficiency standards for external AC/DC power supplies coupled with dedicated energy consumption testing in integration mode for standards like Energy Star and CEC. It also offers a complete solution for full compliance testing to IEC 62301 standby power requirements. The instrument's 1 MHz bandwidth supports the LED module energy certification requirements of CQC-3146, as well as harmonic analysis on wireless chargers with kHz level fundamental frequencies on the transmitter and receiver.


To support a wide range of applications, the PA300 includes more than 50 standard measurement functions, including harmonics, frequency, and star-delta computation and has multiple analogue and digital inputs for sensor data such as thermocouples, speed sensors, and torque sensors. Built-in ±15V supplies for external transducers support high current applications.


The PA3000's full colour display shows measured values, waveforms, harmonic bar charts and energy integration plots. Setup is via a menu-driven interface and soft keys. Included PWRVIEW software automates instrument setup and enables data collection, analysis, and report generation with wizard-driven interfaces. Pricing starts at $7,000.
