WebbUsing FastFrame Segmented Memory in the DPO7254 oscilloscope, the pulses are captured at a sample rate of 20 GS/s with the same small record length as shown in Figure 1. The segmented memory has been overlaid so all of the pulses appear stacked on top of one another on the screen. Advantages of this approach include: Figure 3.

"WebbLow frame rate Figure 1. A SlowFast network has a low frame rate, low temporal resolution Slow pathway and a high frame rate, higher temporal resolution Fast pathway. The Fast pathway is lightweight by using a fraction ( , e.g., 1/8) of channels. Lateral connections fuse them. For example, waving hands do not change their identity as " - Slowfast frame length x sample rate
