MEASURING APPARATUS, MEASURING METHOD AND TEST APPARATUS
First Claim
1. A measurement apparatus comprising:
- a first timing detecting section that detects first change timings of a signal under measurement;
a second timing detecting section that detects second change timings of the signal under measurement;
a buffer section that buffers data indicating the first change timings detected by the first timing detecting section and data indicating the second change timings detected by the second timing detecting section; and
a calculating section that acquires, from the buffer section, the data indicating the first change timings and the data indicating the second change timings, calculates a temporal relationship between the first change timings and the second change timings, and outputs the temporal relationship.
