10µHz–35MHz Versatile High Performance Gain/Phase Frequency Response Analyzer
Utilising an innovative design that incorporates both direct digital analysis and heterodyning techniques, the PSM1735 provides a broad range of measurement functions over a wider frequency range than any other instrument available today. Typical applications for this product include switched mode power supply feedback loop analysis, filter test and design, LVDT testing, sweep frequency response analysis of wound components and much more. As with other N4L products, PSM1735 NumetriQ utilises the latest DSP and FPGA technology to optimise the use of its analogue hardware providing speed and measurement flexibility without compromise on the performance of each measurement function. The N4L PSM1735 features 0.01dB gain accuracy and 0.02° phase accuracy which is truly market leading performance.
