When we attempt to capture multiple RF bursts that are separated by 4.0 ms, the
scope under-samples and shows varying amplitudes of the signal as shown in
Figure 16 . Again, this is because the scope automatically reduced its sample rate
in order to capture a longer time-span with its limited amount of acquisition
memory. Let’s now zoom-in and take a closer look at this under-sampled data.
