Oscilloscopes & Spectrum Analyzers

Oscilloscopes & Spectrum Analyzers

As technologies advance across all sectors, test and measurement equipment is called upon to analyze and validate device performance with increasing precision. This requires an accurate and robust timing reference to measure against. SiTime MEMS timing solutions provide the stability engine needed for clock synthesis. In addition to proving better stability and lower wander, SiTime MEMS-based TCXOs and OCXOs have better aging specifications, extending equipment accuracy over the long term and increasing its value.
