Any suggestion on the best settings to use (particularly the PLC integration and filtering) to get the best accuracy and resolution for DC measurements with a 3456A where reading speed isn't an issue? John

The statistical functions work well to enhance less accurate PLC without having to endure slower reading speeds; the more samples you obtain the more the true value regresses to the mean and correct per measurement variations. Empirically I find that the stat functions give readings very close to the best PLC but avoids the slower update rates. Variance is very helpful once converted to standard deviation to determine the most reliable LSD and the spread of the measurements obtained [ sq. root of variance = standard deviation.] At 12:54 PM 9/11/2011, John Ackermann N8UR wrote: >Any suggestion on the best settings to use (particularly the PLC >integration and filtering) to get the best accuracy and resolution >for DC measurements with a 3456A where reading speed isn't an issue? > >John
