Tough Power-Related Challenges

In the current era, engineers are striving to enhance efficiency in electronic power conversion systems, including AC/DC power supplies, DC/DC converters, and more. They need to ensure their designs meet set goals, operate efficiently, and behave appropriately under transient conditions. Traditional power measurement instruments fall short in providing accurate dynamic measurements. The Keysight PA2201A IntegraVision power analyzer is an ideal solution for engineers who need to measure AC and DC power consumption, power conversion efficiency, and common AC power parameters quickly and interactively – all with 0.05% basic accuracy and 16-bit resolution. It also characterizes power consumption under highly dynamic conditions with 5 million samples per second digitizing speed and 2.5 MHz bandwidth.

The Keysight PA2201A IntegraVision power analyzer is user-friendly, with an interface based on familiar oscilloscope modeling so you'll experience a short learning curve. All inputs are isolated from each other and from the chassis ground, allowing for easy connection. It simultaneously captures voltage and current on all channels, providing real-time instantaneous power waveform display and power measurement.

The power analyzer supports the capture of voltage, current, and power waveforms over specific periods of time. This is particularly useful for examining transient phenomena and in the design of periodically controlled equipment. It is crucial to measure power consumption across a range of different modes from sleep to full activity, to ensure compliance with energy standards.

The power analyzer can be set up to make single-shot measurements to capture and measure transient phenomena. Power analyzers use mathematical transformations to analyze signals. For precision, the measurement window cannot have any discontinuities or gaps. Continuous Whole-Cycle Analysis (CWA) used by the PA2000 Series, is a gapless measurement technique that always performs measurements on a positive integer number of signal cycles.

Measuring Power: Power Analyzer or Oscilloscope?

Engineers working on electronic power conversion systems require high-accuracy measurements to identify and characterize incremental efficiency improvements in devices. While some of today’s power analyzers offer adequate measurement accuracy, they lack the ability to characterize power consumption under dynamic conditions. Previously, engineers needed a power analyzer to make accurate measurements and an oscilloscope to visualize repetitive and single-shot events.

Precision power analyzers like the Keysight PA2201A offer high accuracy and ease of connection to the DUT, making them ideal for steady-state measurements of power consumption, efficiency, and power quality. Traditionally, only oscilloscopes offer the single-shot measurement capability necessary for dynamic measurements during functional tests. However, their lower accuracy means that making critical efficiency measurements on high-efficiency converters may not be possible.

R&D engineers are forced to switch between these two instruments depending on the type of measurement they need to make. They use a power analyzer to make accurate measurements and an oscilloscope to visualize repetitive and single-shot events. Switching between instruments is time-consuming and makes it difficult to get consistent, reproducible results.

Channel Connections for Voltage and Current Inputs

• Simultaneously digitize voltage and current with voltage inputs and current inputs on every channel.
• Connect via floating voltage and current inputs that are isolated to 1000 V from each other and from the chassis ground, allowing a connection without the need for differential probe or the danger associated with floating a ground-referenced instrument.
• Directly measure current up to 2 A and up to 50 A using built-in current shunts with fully specified and calibrated performance.

Transients

• Capture one-time events (like a startup) or transient events (like cycle dropout) to visualize and perform analyses.
• Use edge triggering on voltage, current, or power signals for easy synchronization with an event like startup, in-rush, or spikes.
• The 10 MHz Reference input and the Trigger input and output are 0 to 3.3 V logic level (5 V max).
• The Trigger-out connection has a 50 ohm output impedance.
