Serial Bus Decoding & Triggering, Search & Navigation, and Segmented Acquisition Labs 4
4000 X-Series Oscilloscopes Advanced Training Guide 85
The white triangles near the top of the waveform area mark the time
location of each “found” occurrence of our search operation as shown in
Figure 53. These frames are also marked in orange in the first/pointer
column of the lister table. Your scope should have found and marked
approximately 25 occurrences of this search operation based on a total
acquisition time of 200 ms. Note that the number of “found” events is
indicated near the bottom of the display. To automatically navigate to each
frame with a “Missing Acknowledge”, press the and front panel
navigation keys near the timebase controls.
Let’s now use the scope’s Segmented Memory mode of acquisition to
selectively capture 500 consecutive occurrences of our trigger condition
(Read from address 29
HEX
). But to complete the rest of this lab your scope
must be licensed with the Segmented Memory option.
31 Push the horizontal position/delay knob to re- position the trigger point
back to center-screen.
32 Set the scope’s timebase to 100.0 µs/div.
33 Press the [Run/Stop] front panel key to begin repetitive acquisitions
again.
34 Press the [Acquire] front panel key.
