一、产品简介

The PPA4500 features high speed FPGA/DSP sampling techniques and N4L’s highly respected “Planar Shunt” Technology, the PPA4500 is the result of over 12 years of development. The PPA4500 replaces the outgoing PPA2500 and PPA2600 models, with improved accuracy, colour TFT, front USB port and faster processing. The PPA4500 is a significant leap forward in both accuracy and functionality. 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 **p 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 Utilises parallel digital filtering for fundamental frequency synchronisation without affecting the bandwidth of the measured data. All PPA4500 units are shipped with UKAS ISO17025 certification as standard, this is performed at N4L in the UK in our accredited ISO17025 Laboratory.
