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.
