As stated in PXIe-4302 User Manual (NI Document 377003a):
External Clock
The NI PXIe-4302/4303 ADCs cannot be clocked from external sources such as encoders or
tachometers. However, signal processing features in the Sound and Vibration Measurement
Suite often provide an excellent alternative to external clocking in encoder and tachometer
applications. Visit ni.com/soundandvibration for more information about the Sound and
Vibration Measurement Suite.
Is this true of all Sigma Delta ADCs?
If this is true, are there any other hardware methods one can use have an encoder be the external clock the AI sampling?
