PSM1700 Frequency Response Analyzer

psm1700

PSM1700 PsimetriQ is a comprehensive DFT and true RMS analysis instrument for R&D and production test applications. Specifically aimed at a range gain/phase analysis applications, amongst which include switched mode power supply feedback loop stability analysis and general frequency response analysis of filters. It has a clear, bright graphics display showing real time values or graphs or tables. It can be operated completely by remote control over RS232 or LAN as an option. When combined with the IAI (Impedance Analysis Interface) the PSM become a high accuracy 1MHz Impedance Analyzer/ LCR meter. It is designed to give optimum performance, speed of measurement and convenience, providing sophisticated measurement capability in a cost effective and easy to use bench top instrument.

PSM1735 – 10uHz to 35MHz Frequency Response Analyzer

psm1735

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.

PSM3750 Frequency Response Analyzer

psm3750

The 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.

SFRA45 Sweep Frequency Response Analyzer

sfra45

The SFRA45 is a Sweep Frequency Response Analyzer with a bandwidth of 5Hz to 45MHz, the SFRA45 offers a fully portable solution for the field of SFRA (Sweep Frequency Response Analysis) which fully complies with IEC60076-18 – Power Transformers Part 18 - Measurement of frequency response.

Featuring an inbuilt colour LCD screen as well as being battery powered, the tablet style instrument can be used with or without PC Software. The dedicated software available (SFRAComm) enables the user to create databases from which historical transformer sweeps can be recalled and compared to current sweeps for analysis. This offers the ability to perform the most common sweep frequency response analysis technique “Fingerprint Comparison” as well as all other comparison techniques.
