PSM1700 Frequency Response Analyzer

10µHz–1MHz Versatile High Performance Gain/Phase Frequency Response Analyzer

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.
