Uncompromising Analysis Capability
Many USB users have been using digitizer hardware with software that simulates
an oscilloscope for test and troubleshoot implementation. The limitations of this
configuration are often overlooked, but they can cause signification problems. When a
instrument says it has a high waveform update rate, people usually expect it to have a
higher probability of catching random and infrequent glitches, but this isn’t the case for
those instruments. In addition, common measurements like waveform averaging and
advanced waveform triggers are not available.
The Keysight Streamline Series USB oscilloscopes USB oscilloscopes require minimum
support from a central processing unit (CPU), as most of their core operations are
handled by the MegaZoom IV smart memory ASIC, which is Keysight proprietary
technology. MegaZoom includes hardware serial decoders and hardware mask/limit
testing capability; supports GUI operation; and integrates additional instruments like a
WaveGen function/arbitrary waveform generator.
The P924xA USB oscilloscopes utilize hardware to perform many of the functions
traditional digitizers do with software on the CPU. By doing more in hardware, P924xA
Series oscilloscopes can analyze more of the signal than ever before.
Key to the oscilloscope operation is that the acquisition does the triggering and most of
the analysis utilizing onboard hardware. For example, to accomplish 1million waveforms/
sec, the waveforms are captured and plotted into hardware on the scope and then the
waveform is transferred to the PC for display.
