Parameter Measurements
Besides parameter measurements made during acquisition, post-
acquisition measurements can also be made. The number of parameters
available depends on the options loaded on your instrument.
Measurements are made only on the events defined by your filter (search
criteria). A
Filter Wizard is provided to quickly establish statistical criteria
such as ±1, 3, or 5 sigma.
Sampling Mode
Whenever WaveScan is enabled, the instrument reverts to Real-time
sampling mode.
S OURCE V IEW
The top trace on the screen is the source (channel, math, memory) trace.
This trace shows all captured edges and highlights those that fit your search
criteria. For example, in this figure we are searching for slow rising edges
that fall outside a time window:
In this acquisition, WaveScan has located eleven edges that fit the search
criteria (filter) of greater than 1.2 ns with a delta of 50 ps. Each of the
found edges is highlighted with a red rectangle, and indexed to a table
entry at left. Rise time values are also included in the table.
Level Markers
Markers are provided on the source trace to show measurement criteria
such as level and thresholds. In the example above, the level markers
indicate 10% and 90% for the standard Rise Time parameter measurement.
Level markers are displayed only while the scope is in WaveScan mode.
Once the WaveScan Enable checkbox is unchecked, the level markers
disappear.
