12 Using Segmented Memory Acquisition to Capture More Data
62 Agilent InfiniiVision 7000B Series Oscilloscopes Evaluation Guide
It may appear that the oscilloscope is capturing a repetitive low-cycle
pulse. But it is actually capturing a burst of pulses. You can re-scale the
timebase to 1.0 µs to view the burst of pulses. To capture and compare
multiple bursts of signal activity, you could re-scale the timebase to
capture a longer time-span. However, with limited acquisition memory
(8M on InfiniiVision Series oscilloscopes) the oscilloscope would
automatically reduce its sample rate to capture the longer time-span.
This would reduce measurement accuracy. Another alternative would be
to use the oscilloscope’s Segmented Memory acquisition mode. Let’s
now set up a Segmented Memory acquisition to capture 150 consecutive
occurrences of this burst of signals.
7 Set the timebase to 500 ns/div and the horizontal delay to 1.700 µs.
8 Press [Acquire].
9 Press Segmented; then, select 150 (# of Segments).
10 Now press Segmented to begin a Segmented Memory acquisition.
