NI PXIe-4357 Features
For increased performance, the NI PXIe-4357 shares its RTD inputs across five different ADCs
and supports multiple timing modes in order to balance the trade-offs among speed, accuracy,
and noise rejection.
The NI PXIe-4357 channels are multiplexed to the corresponding ADCs as shown in Table 2-3.
The NI PXIe-4357 is isolated from the PXI Express chassis and from other modules in the
system.
