Using Segmented Memory Acquisition to Capture More Data 12
Agilent InfiniiVision 7000B Series Oscilloscopes Evaluation Guide 63
The oscilloscope should have just captured 150 consecutive waveform
segments with Segment #1 shown on-screen. Let’s now review all of the
waveform segments and determine how long of a time-span the
oscilloscope just captured.
11 Press Current Seg.
12 Review all 150 waveform segments by rotating the selection knob.
13 Rotate the selection knob until Segment #150 is selected and shown on
screen.
Notice that each segment/burst has been time-tagged with a time value
relative to the first captured segment (Segment #1). Segment #150
should have a time-tag of approximately 149 ms. Capturing this much
waveform information at a high sample rate using conventional
acquisition memory would be impossible. Let’s now see how Segmented
Memory can be used on packetized serial bus signals.
