The video tracking adjustment, typically done with an analog oscilloscope, requires a lively, gray-scale display. The measurements discussed highlight some of the oscilloscope's capabilities for design debugging, signal characterization, and verification of compliance with industry standards. Examples of new measurements enabled by this technology are described.
All digital systems are concerned with adequate timing margins.
As clock speeds in communications and semiconductors continue to increase, timing margins get even narrower. This application note shows the results of measuring a 17.5 ps edge and a 500 MHz clock using oscilloscopes with different bandwidths. Couple this with the statistical analysis capabilities of the DPO oscilloscope, and you have a very effective jitter analysis tool. In applications requiring both high sample rates and long record lengths, adding more memory is not always the answer. In situations where a series of infrequent or intermittent events are to be captured, the TDS FastFrame function provides an ideal means to capture only the necessary events.
