Abstract:

A converter for adapting a longitudinal mode, fiber optics cathode ray tube recorder, or visicorder, to operate selectively in either the longitudinal, Y axis mode or in the transverse, X/Z axes mode. The data to be recorded is displayed, initially, upon a control oscilloscope. Samples of the horizontal sweep and gate signals of the control oscilloscope are directed to the converter. Therein, the horizontal sweep signal is conditioned and amplified to provide the high current linear ramp signal necessary to drive the horizontal yoke of the visicorder. The data is synchronized with the gate signal to ensure identity between the visual display on the control oscilloscope and the data recorded by the visicorder. The converter also includes circuitry for selectively printing start and end of trace markers, a time line marker, and external time code data in association with the recorded data, to facilitate its subsequent analysis and identification.
