Doble M5400 Sweep Frequency Response Analyzer

The Doble M5400 Sweep Frequency Response Analyzer reliably evaluates and provides detailed information on the performance of transformers and reactors. The Doble M5400 analyzer conducts in-depth tests on equipment that uses windings, comparing the results to baseline readings for immediate analysis. This sweep frequency response analyzer removes any confusion with transformer performance, identifying all possible issues within the equipment.

A Doble M5400 Sweep Frequency Response Analyzer delivers a maximum sampling rate of 100 MS/s along with an input and output impedance of 50 Ω. The vast frequency range of 10 Hz to 25 MHz allows the Doble M5400 to cover a range offering the greatest diagnostic value.
