1. A waveform measurement and display apparatus, comprising:
- a first and second signal-processing channel, each including means for converting a respective electrical signal to digital representations thereof, digital memory means for storing said representations, and means for converting said representations to analog values for display;
means for selectively providing a Y-T display wherein at least one of said first and second signals is displayed along a time axis, and an X-Y display wherein said first signal is displayed along a first axis with respect to said second signal displayed along a second axis normal to said first axis; and
means for storing time marker data at predetermined address locations and producing time markers at corresponding time positions of said Y-T and X-Y displays.

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.
