Read the Timestamp Column

In detailed mode, where each line represents a single capture event, the timestamp value represents the time elapsed between the event on that line and the event on the previous line. So, if you want to determine the time elapsed between the capture of the first event and the fifth event, add up the timestamp values on the second, third, fourth, and fifth lines. Alternately, you can switch to an inactive display using the Switch to Inactive Display button and put markers on the first and last event of interest, then use the From and To fields in the Markers & Statistics group box to have the GPIB analyzer calculate a Time elapsed value for you.

In summarized mode, where more than one event can be present on a line, the timestamp value represents the time elapsed between the first event on that line and the first event on the previous line.

The timestamp column in the capture display shows the timestamp in a minute, second, millisecond, microsecond, and nanosecond notation. If the timestamp exceeds 60 minutes, the timestamp is shown in an hour, minute, and second notation. The abbreviations used for the various time scales are listed in the following table. The smallest recordable timestamp is 50 ns.
