Method and apparatus for determining linearity of a ramp signal

摘要

An improved system and method of determining the linearity of a ramp signal, including a ramp generator (11) for generating a ramp signal and a vernier delay (15) to provide scan stop signals where the samples are peak detected (17) and stored (21). The ramp generator (11) outputs are divided into equal sections controlled by a precise crystal controlled oscillator (25). The stored signals are processed and compared to detect errors.
