Frequency response analyzer 1250E

The 1250E Frequency Response Analyzer (FRA) delivers accurate measurement of gain and phase. The device under test is stimulated by a sinewave and the response analyzed at various points in the system. These responses are then correlated with the stimulus to determine the amplitude and phase relative to the generator. The ratio of the two measured signals can then be used to provide the system transfer function. This process rejects all harmonics and, by increasing the integration time to further reject noise and interference, even signals which are buried in noise can be measured accurately. The 300 V range on the 1250E is particularly useful for making measurements on fuel cell stacks and high voltage batteries, used in hybrid vehicles and residential power supplies. Key product features include:- - AC amplitude range - 10 mV to 10 V, for power supply testing - Analyzer range 30 mV - 300 V, i.e. suitable for ATS (Automated Test Systems), power station vibration testing - Noise rejection capability - Synchronizer option enabling generator and carrier signals to be locked to external signals in terms of frequency / phase - Ability to analyze non-linear systems (harmonic analysis) - Front panel or PC software control - Modulator / demodulator option for interfacing to AC carrier systems
