Oscillographic scale-time transformer



Single and infrequent pulses with 0.1 … 100 V amplitude and 2·10-10…5·10-7s length detection.

Principle of operation

Time-scale transformer is a complex, consists of PC with TV I/O and transforming unit, fast oscillograph DDD and TV camcorder with CCD-matrix. Special software module form pulse signal for oscillograph preparing for realization registration for processes synchronizing, then form a signal for external devices to start. Taken oscillogram image is extracted from registered continuity, than filtered and vectorized. One can automatically transfer estimated values in PC net.

Developed registered oscillogram geometrical errors correction method ensure registered signal estimates error less than 2%. This allow us to use scale-time transformer as master gage.
