Recording and Reproducing Transients for Frequency Domain Analysis

An EMC laboratory has frequent need for performing frequency analyses of single-shot transients, a task that usually entails recording the transient so that it can be repeatedly reproduced electrically for analysis. Convair has provided this capability over a wide range of conditions, either by using the Waveform Synthesizer to reproduce and analyze the transient; or by using the Compatiblity Analyzer to compute the spectrum and a Model 702 for providing a time-scaled transient to it. Input to Model 702 can either be automatic on-line or manual from a visual recording such as a photograph.
