SENSe Subsystem 16Keysight U2040 X-Series Programming Guide 213[:SENSe[1]:]AVERage:COUNt:AUTOSyntax[:SENSe[1]:]AVERage:COUNt:AUTO ON|OFF|1|0[:SENSe[1]:]AVERage:COUNt:AUTO?DescriptionThis command enables and disables automatic averaging.When the auto filter mode is enabled, the U2040 X-Series automatically sets the number ofreadings averaged together to satisfy the averaging requirements for most powermeasurements. The number of readings averaged together depends on the resolution andthe power level in which the U2040 X-Series is currently operating. Refer to Figure 1-2 forthe typical number of averages for each range and resolution when the U2040 X-Series isin the auto-filter mode and set to the normal speed mode.Setting this command to ON automatically sets the [:SENSe[1]:]AVERage:STATecommand to ON.If [:SENSe[1]:]AVERage:COUNt:AUTO is set to OFF, the filter length is set by[:SENSe[1]:]AVERage:COUNt. Using [:SENSe[1]:]AVERage:COUNt disablesautomatic averaging.Auto-averaging is enabled by the MEASure:POWer:AC? and CONFigure:POWer:AC?commands.The query enters a 1 or 0 into the output buffer indicating whether the automatic filterlength is enabled or disabled.– 1 is returned when the automatic filter length is enabled– 0 is returned when the automatic filter length is disabledExampleNOTE For most applications, automatic filter length selection([:SENSe[1]:]AVERage:COUNt:AUTO ON) is the best mode of operation. However,manual filter length selection ([:SENSe[1]:]AVERage:COUNt ) isuseful in applications requiring either high resolution or fast settling times, where signalvariations rather than measurement noise need filtering, or when approximate results areneeded quickly.AVER:COUN:AUTO OFF Disables automatic filter length selection.
