Schlumberger 1250 Frequency Response Analyzer

Description

Description

The 1250 Frequency Response Analyzer makes precise measurements of gain and phase. The 1250 features an internal synthesized function generator and 2 parallel input channels. The 1250 stimulates the device under test and analyzes the response at one 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 1250s applications include analysis of non-linear systems, transducer and control system characterization, electrochemistry, and materials testing. An optional synchronizer permits locking the 1250 to rotating or reciprocating machinery for applications such as turbine analysis. A modulator-demodulator and plotter interface are also available.
