Uncompromising Analysis Capability
Many modular 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.
Keysight is currently the only vendor that delivers oscilloscope hardware in a PXI
modular package. Keysight’s M924XA Series PXIe oscilloscopes begin with basic digitizer
hardware, but then they add measurement tools directly into the hardware of the PXI
card.
The InfiniiVision PXIe modular 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; plots analog and
digital data directly to the display; supports GUI operation; and integrates additional
instruments like a WaveGen function/arbitrary waveform generator.

The M924XA Series PXIe modular oscilloscopes utilize hardware to perform many of the
functions traditional digitizers do with software on the CPU. By doing more in hardware,
M924XA Series oscilloscopes can analyze more of the signal than ever before.
