|NI-DCPower (English | Japanese)|
The NI PXI-4132 can average multiple samples together to reduce noise and improve sensitivity.
|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.
