Keysight achieves this industry-leading waveform update rate with

MegaZoom IV smart memory technology

Traditionally, CPU processing was the major bottleneck for oscilloscope waveform

update rate and responsiveness. Typically, the CPU handles interpolations, logic channel

plotting, serial bus decoding, measurements and more, and the waveform update rate

drops dramatically as these features are turned on.

The InfiniiVision 4000 X-Series requires minimum support from a CPU, as most core

operations are handled by Keysight proprietary technology, the MegaZoom IV smart

memory ASIC. MegaZoom includes hardware serial decoders and hardware mask/

limit testing capability, plots analog and digital data directly to the display, supports

GUI operation, and integrates additional instruments like the dual-channel WaveGen

function/arbitrary waveform generator.

Figure 6. The 4000 X-Series oscilloscopes’ uncompromised responsiveness, speed and waveform update rate is enabled by the MegaZoom IV, smart

memory ASIC. The CPU is not used for core waveform operations.
