NOTE : If you select a different channel mode, the information shown on the
left of this setup display is updated to match acquisition details for your

Trigger
The Trigger setup button opens a pop-up window used for configuring
trigger conditions for the digital device. The trigger pop-up has four tabs for
different trigger categories.
NOTE : It’s important to note that the trigger logic always runs at a rate of
500 MHz under all modes, regardless of the selected Sample Rate. This
allows you to continue triggering on fast events even when lowering the
Sample Rate to obtain a longer timeframe of data. However, this may result
in trigger events that cannot be seen in the slower sampled acquisition
data when presented on the waveform display area.
NOTE: Please ensure that the logic thresholds selected in the Instrument
menu are appropriate prior to configuring triggers and performing
acquisitions. Thresholds that are inappropriate for your signal levels may
result in errant trigger events.
