Real time mode, average detector

Dear,

When operating an SM200C in real time spectrum mode, what is averaged when the detector is configured in average mode?

From my testing that he is doing the averaging of the power but I did not find the information in the documentation and you cannot configure it as for the sweep mode.

An when you are doing the average in power mode, is it average really the power in linear scale (mW) or in log scale (dBm)? If I understand correctly the documentation, for me log is the average in dBm but it would be nice to have a confirmation.

Best regards.

RAlbert,

In sweep mode, ‘Power’ averaging will perform averaging in mW units and ‘Log’ averaging will average in dBm units.

In real-time, averaging is always performed in mW units.

There is a separate type of averaging when you select “Average” for your trace type, that will average the traces together in their final unit type, which is typically dBm.

Let me know if you have follow up questions,
Andrew
