The PSM3750 builds upon the success of our PSM17xx series frequency response analyzers plus our experience in power metrology, to produce a world leading frequency response analyzer. Combining a 13.5-decade frequency range of 10µHz to 50MHz, with isolated generator and 2 or 3 isolated measurement channels, the PSM3750 leads in its field. A seamless change from direct digital analysis to heterodyning as the frequency increases, ensures precision and noise rejection, while galvanically isolated input channels with 16 ranges from 3mV to 500Vpk, provide huge application flexibility. In conjunction with a range of accessories, functions derived from relative voltage and phase include frequency response, impedance, phase angle voltmeter and power. PSMComm PC software provides control and data presentation plus export of measured results to a text file or spreadsheet.
