The Only General Purpose Clock Tool Available
Interact with colleagues on familiar terms: Frequency, Amplitude or Time
*Translate domains using the “Rosetta Stone” of instruments
*Address requirements of Telecom, SONET, Military/Aerospace and PC/Server datacom markets
*Meet the widest range of oscillator test specifications


The Wavecrest SSA-20, SSA-50 and SSA-150 Signal Source Analyzers enable clock, PLL and oscillator manufacturers to expand into new markets such as Telecom, SONET, Military/Aerospace and PC/Server datacom by providing all the tools needed to meet a wide range of test specifications in just one, easy-to-use instrument.

Historically, three to four instruments such as spectrum analyzers, phase noise analyzers, jitter analyzers and oscilloscopes would have beennecessary to cover the test specifications required for today's modern clock devices. Since each of these instruments use different methodologies to provide their individual measurements, and each use unique terminology, it has been virtually impossible to correlate results.

Now with the Wavecrest Signal Source Analyzer, just one instrument is needed to measure in three domains, Frequency, Amplitude and Time. The SSA uses industry-familiar terminology and visually recognizable plots so that designers can easily understand and interpret all of the results. The SSA can also translate results from any one of the three domains to the other, making it the "Rosetta Stone" of oscillator analysis instruments.
