Overview
Triggering, Clocking, and Synchronization
The National Instruments PXI-5124 high-resolution digitizer
features two 200 MS/s simultaneously sampled inputs channels with
12-bit resolution, 150 MHz bandwidth, and up to 512 MB of
memory per channel in a compact 3U PXI module. The NI PXI-5124
uses the high-speed PCI bus and the scatter-gather bus mastering of
the NI MITE ASIC to move data to the computer at speeds up to 100
times faster than traditional instrument interfaces, thereby
dramatically decreasing overall test time. With the Synchronization
and Memory Core (SMC) architecture of the PXI-5124, you can
create mixed-signal systems using signal generators and digital
waveform generator/analyzers or build a high-channel-count
digitizer with subnanosecond synchronization between channels.
