Uncovering Signal Anomalies with Responsive Deep Memory

28

Keysight Infiniium 9000 Series Oscilloscope Evaluation Guide

Take advantage of deep memory: zoom in on one of the glitches to see the

details:

Step 1:

Using the small Horizontal position knob, move one of the glitches to

the center of the display.

Step 2:

Using the large Horizontal time/div knob, set the time base to

500 ns/div (turn clockwise) to see characteristics of the glitch in detail.
With up to 10 Mpts of deep memory you are able to see the big picture

(envelope of the entire AM signal) as well as zoom in on the details of this

anomaly while maintaining a high sample rate.
