Oscilloscope Theory of Operation

There are two different measurement engines in the SIA-3000 that perform specific measurements using

the most appropriate hardware techniques. The Sampling Oscilloscope uses circuitry optimized for voltage

measurements (Amplitude Engine). Timing and Jitter measurements use different internal circuitry optimized

for time measurements (Timing Engine). For amplitude measurements and rise or fall time measurements

(which are amplitude dependent) the Oscilloscope uses a standard Repetitive Sampling methodology. This

allows eye-masks to be created. The time measurements made for the other tools, such as histogram,

are

not

derived from the measurements that this oscilloscope makes.
