High Accuracy 0.01dB 35MHz | PSM1735

High Accuracy 0.01dB 35MHz – Overview

Utilising an innovative design that incorporates both direct digital analysis and heterodyning techniques, the High Accuracy PSM1735 provides a broad range of measurement functions over a wider frequency range than any other instrument available today. Typical applications include switched-mode power supply feedback loop analysis, filter test, and design, LVDT testing, sweep frequency response analysis of wound components, and much more. The PSM1735 NumetriQ utilises the latest DSP and FPGA technology to optimise the use of its analogue hardware providing speed and measurement flexibility without compromising the performance of each measurement function. The N4L PSM1735 features 0.01dB gain accuracy, 0.02° phase accuracy, and a frequency range of up to 35 MHz.
