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�
