High-Speed Digitizer
The NI PXI-5621 is a DC-coupled 64 MS/s 14-bit high-speed digitizer.
Except for its DC coupling, the PXI-5621 is functionally identical to the
PXI-5620. Refer to the
NI PXI-562x User Manual
for instructions on
installing and using your NI PXI-5621.
The NI PXI-5621 specifications are warranted at 0–50
°
C ambient unless
otherwise specified, and include a 10 minute warm-up time from ambient
conditions.
