The NI PXI-4132 can average multiple samples together to reduce noise and improve sensitivity.

Tip Tip  Increase aperture time before increasing the number of samples to average to provide the optimum power line frequency rejection.

You can set the number of samples to average programmatically using the niDCPower Samples To Average property or the NIDCPOWER_ATTR_SAMPLES_TO_AVERAGE attribute. The maximum value is 127. When the number of samples to average is set to N, N samples are acquired and the results of all the samples are averaged together to return a single measurement.
