Newtons4th Ltd PSM3750

Newtons4th Ltd PSM3750 builds upon the success of the PSM2200 and PSM17xx series of frequency response analyzer ranges and combines the experience gained from the design and development of our power analyser range of isolated input channels in order to provide a solution for high voltage, high accuracy, isolated gain, and phase measurement.

Utilising an innovative design that incorporates both direct digital analysis and heterodyning techniques within 500Vpk galvanically isolated input/output channels, the PSM3750 provides a broad range of measurement functions over a wider frequency range than any other instrument available today.

As with other N4L products, PSM3750 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.
