Power Analyzers

N4L - General Purpose Power Measurement

The PPA500 from Newtons4th adds to the company's range of Precision Power Analyzers by meeting the demand for a high-performance, cost-effective power analyzer. Designed primarily for applications needing precise measurements without intricate features, it finds utility in educational, production, or testing contexts. The unit features a full-color TFT display, providing superior flexibility over numeric displays. Despite its compact half rack width and 2U height, it offers up to 3 phase configurations and can be mounted in a 19-inch rack, allowing for expanded capabilities. Key features include the planar shunt and FPGA-based real-time no-gap analysis techniques, which are foundational to its performance. Each PPA500 comes standard with a UKAS ISO17025 certification, validated by bespoke power calibrators ensuring accuracy across its frequency range. The low cost and high reliability of the PPA500 make it a valuable choice for system integrators who require dependable power analysis with traceable accuracy.

Frequency Response Analyzers

Frequency Response Analyzer

The PSM1700 Frequency Response Analyzer, under the PsimetriQ brand, is a versatile instrument designed for gain and phase frequency response analysis across a frequency range of 10µHz to 1MHz. Targeting R&D and production test applications, this analyzer is ideal for tasks such as switched mode power supply feedback loop stability analysis and the general frequency response analysis of filters. The PSM1700 features a clear graphical display capable of showing real-time values, graphs, or tables, and can be remotely controlled via RS232 or optional LAN interfaces. When combined with the Impedance Analysis Interface (IAI), the PSM1700 transforms into a high-accuracy 1MHz impedance analyzer and LCR meter. The device is optimized to deliver high performance, rapid measurement capabilities, and user-friendly operation, making it a cost-effective choice for bench-top testing of control loop stability, transistor performance, filter design, audio amplifier design, optocoupler evaluation, coax cable frequency response, LDO regulator assessment, signal transformer performance evaluation, cross-talk testing, and RFI/EMC filter design.
