High-Performance Power Analyzer PPA4500 Overview

The PPA4500 features high-speed FPGA/DSP sampling techniques and the highly respected “Planar Shunt” Technology, the PPA4500 is the product of over 12 years of research and development. The PPA4500 is better than the outgoing models, with improved accuracy, color TFT, front USB port, and faster processing. The PPA4500 is a significant leap forward in both accuracy and functionality. The PPA4500 is well suited to transformer loss testing, PWM inverter drive efficiency testing, standby power testing to IEC62301/EN50564, and many more challenging applications.

The PPA4500 exhibits the ability to measure fundamental frequencies up to 2MHz, as well as up to 100 Harmonics with the same 2MHz upper-frequency limit. PWM Motor drive mode enables the engineer to rapidly set up the instrument to measure complex harmonically distorted waveforms, sophisticated signal processing algorithms facilitate high sample rate (2Ms/s) true wideband (2Mhz) analysis of PWM signals. The PPA4500 utilizes parallel digital filtering for fundamental frequency synchronization without affecting the bandwidth of the measured data.
