<p>Self-calibrating, edge-triggered time measurement apparatus including a precision crystal oscillator (22); rough counter means (66) start and stop, capacitive ramp vernier means (62; 64); a fine count memory; a display; and processor means (2) for computing repetitive and non-repetitive event interval data. Asynchronous start and stop event portions are addressably determined relative to the fine count memory (4) upon conversion of resultant ramp voltages. The initial event and clock measurement edge are also separately selectable.</p> |
