TEST AND MEASUREMENT INSTRUMENT, AND METHOD IN TEST AND MEASUREMENT INSTRUMENT

摘要

PROBLEM TO BE SOLVED: To enhance probability of detecting an event occurring between a data sampling period and another data sampling period.SOLUTION: When a data sampling period occurs is made movable relative to a frequency transform processing period. A data sampler captures first sampled data, and a frequency transform processor 640 applies frequency transform processing to the first sampled data during a first data processing period. A capture time adjustor 654 controls when in the first data processing period the data sampler captures second sampled data, in accordance with user instructions. When to capture the second sampled data may also be determined by using a probability distribution function.
