ABSTRACT:
A waveform measurement and display apparatus comprises a pair of signal-processing channels in addition to a sweep generator arranged so as to provide both Y-T and X-Y display modes. A time marker generator system is provided to insert time markers into the same relative time positions of the respective Y-T and X-Y displays so as to precisely ascertain the time relationship between the two displays. Additionally, such time markers may be inserted into corresponding time positions for expanded and unexpanded waveforms in the Y-T display mode so as to precisely ascertain the relative time position therebetween.
