Triggering

Trigger Setup Menu

The trigger types are Start trigger, Non–Ack trigger and Address trigger. Combination triggers with these I²C bus trigger types can be set using analog signals on other channels.

Analysis

Acquired waveforms are analyzed in a time series, and analyzed results are decoded and displayed one byte at a time. When a cursor is moved over the onscreen data, the corresponding waveform is automatically enlarged in the zoom area.

Waveform and Analysis Results

Search

You can search rapidly for a specified addresses and data pattern in the analyzed results. When the specified data are found, the cursors automatically move to the corresponding location, and the waveform is enlarged in the zoom area.
