11 Segmented Memory
64 Agilent Infiniium 9000 Series Oscilloscope Evaluation Guide
Combining Segmented Memory with Serial Triggering and
Decode
Many serial buses have long periods of inactivity between bursts of
packets. Using segmented memory with serial decode and triggering
enables the oscilloscope to maximize the captured time window.
1 Make the I
2
C demo board connections, perform initial setup, set
up serial decode, and set up the trigger as shown in “I
2
C" on
page 45.
2 Set up the segmented memory acquisition as shown in “Set
acquisition options:" on page 61.
3 Press [Single].
You can see the number of segments acquired in upper left portion
of the screen.
4 Part way through the acquisition, disconnect power to the demo
board to stop I
2
C traffic.
5 Wait a minute, and then re-apply power to the demo board.
When you finish acquiring segments, you will have acquired over a
minute of capture with the help of segmented memory. Time tags
between segments time out at 6.5 days.
