130 4000 X-Series Oscilloscopes Advanced Training Guide
4 Serial Bus Decoding & Triggering, Search & Navigation, and Segmented Acquisition Labs
Let's now use the scope's Segmented Memory mode of acquisition to
selectively capture 500 consecutive occurrences of our trigger condition
(Frame ID = 1). This would be extremely useful if you wished to capture
an entire set of 64 cycles of a particular Frame ID, or perhaps a set of
640 consecutive frames, for troubleshooting and analysis. To complete the
rest of this lab your scope must be licensed with the Segmented Memory
option.
27 Push the horizontal position/delay knob to re- position the trigger point
back to center-screen.
28 Set the scope's timebase to 1.30 µs/div. Do this by tapping the timebase
value on the top of the screen, and tapping it again in the pop up
window. You can use the keypad to enter a custom timebase. Set the
scope's offset to ~- 1.2 µs to center the frame on the screen. This is
done by adjusting Main Delay in the same timebase pop up menu.
29 Tap the Search key to disable the search feature (button light will turn
off).
30 Tap the double- up arrows to the top right of the lister to close the
lister menu,
31 Press the [Acquire] front panel key.
