Query Syntax

:PNOise:CORRelations?

Description

When using two input channels, this command specifies the number of correlations that will be accumulated between averages.

The phase noise single-sideband (SSB) frequency offset plot will average results when acquisitions are running, which will smooth the roughness of the phase noise trace. Increasing the number of correlations will lower the oscilloscope's measurement noise floor but also slow down averaging.
