 An oscilloscopes trigger holdoff specifies how long the scope should pause before responding to new trigger events. Increasing the holdoff is helpful for viewing dense bursts of changes in a signal, like data packets. This signal contains a repeating pair of data packets, each about one millisecond long, with one millisecond between them. Using the default edge mode to trigger display, the packets overlap and roll badly. This is caused by the scope triggering at different start points within the signal. To trigger only at the starting edge of that first packet, we need to increase the holdoff to around three milliseconds, the length of both packets and the space between them. Now the scope won't be thrown off by any additional triggers that occur within the duration of our two-packet sequence.
