Oscilloscope Reference B-Event Scan Setup
B-Event Scan Setup
B-Event Scan is particularly useful for creating overlapped eye diagrams, and applies to all standard
Pinpoint Trigger A- and B-Events sequenced by Trig on nth Event in non-FastAcq mode.
The B -Event Scan initializes the Start Event value to 1 and the End Event value to 8. The Start Event
must be less than or equal to the End Event value. Advance After, advances the B-Event value after the
given numbe
r of acquisitions have occurred depending on the selected Advance method (Sequential,
Random, and Toggle).
When set to Sequential, the B-Event value is sequentially incremented after each acquisition
compl
etes, until the Start Event reaches the End Event. At this point the B-Event value is set to
Start Event value again.
When
set to Random, the B-Event v alue is set to a random value between the Start Event and End
Event v alues for each set of Advance After acquisitions.
Whe
n set to Toggle, the B-Event value alternates between the Start Event and End Event for each set
of Advance After acquisitions.
Th
is process continues and occurs at hardware speed. The range for the B-Event, Start Event, and End
Event is from 1 to 2e9.
