Notes The following legacy parameters to the [:SENSe]:AVERage:TYPE command are aliased as shown:
LINear aliased to SCALar, sets Scalar averaging
VOLTage aliased to SCALar, sets Scalar averaging
VIDeo aliased to LOG, sets Log-Power averaging
LPOWer aliased to LOG, sets Log-Power averaging
POWer aliased to RMS , sets RMS averaging
Initial S/W Revision Prior to A.02.00
More Information
When you select log-power averaging, the measurement results are the average of the signal level
in logarithmic units (decibels). When you select power average (RMS), all measured results are
converted into power units before averaging and filtering operations, and converted back to
decibels for displaying. Remember: there can be significant differences between the average of the
log of power and the log of the average power.
These are the averaging processes within a spectrum analyzer and all of them are affected by this
setting:
