Overview
National Instruments 5124 high-resolution digitizers feature two
200 MS/s simultaneously sampled input channels with 12-bit
resolution, 150 MHz bandwidth, and up to 512 MB of memory per
channel in a 3U PXI or PCI module. NI 5124 devices use 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 an NI 5124, you can create mixed-signal
systems using signal generators and digital waveform
generators/analyzers or build a high-channel-count digitizer with
sub-nanosecond synchronization between channels.

• Edge, window, hysteresis, video, digital, triggering with
50 ps timestamping
• Pre and posttrigger acquisition in single and multiple-record mode
