Combining measurements over time to allow visualization of certain aspects of the input signal or hiding of unwanted signals. All calculations can be reset by selecting the calculation mode again.

As there is no VBW setting for noise reduction, it is advised to use averaging instead.

When averaging or holding is active the calculated value is displayed in a yellow trace. The latest acquired value is displayed in a red trace. Markers take their value from the calculated yellow trace.


The above picture shows the power enveloppe of a mobile phone base station that transmits between 945MHz and 955MHz in the yellow max hold line and the current transmit power in the red line.
