Sweep frequency response analyzer
10 µHz - 65 kHz | 1250B Solartron Analytical

The model 1250B 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 one, two or more 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, even signals which are buried in noise can be measured accurately.

The 300 V range on the 1250B 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 in terms of frequency / phase
* Ability to analyze non-linear systems
* Front panel or software (Visual Basic) control
* Modulator / demodulator card option for interfacing to AC carrier systems
