Search Modes

Use the Mode control to select an appropriate Search to locate anomalies
during acquisition. When each of the following modes are selected, a
corresponding right-hand dialog provides additional controls. The following
modes are available:

Edge Mode – Designed for detecting the occurrence of edges;
selectable slope and level.

Non-monotonic Mode – For detecting threshold re-crosses;
selectable slope, hysteresis, and level.

Runt Mode – For detecting pulses failing to cross a threshold;
selectable polarity and thresholds.

Measurement Mode – For filtering and performing parameter
measurements.

Measurement Mode – Searches from 2 to 64 bits; ideal for bursted
patterns where a PLL cannot lock.

Bus Pattern Mode – Searches from 2 to 64 bits; enhances MSO
search capabilities.

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.
