Overlay two spectrum measurements

[Audio-Creative]

I want to compare two spectrum measurements on one display, how could i do this?
for example: I make a spectrum measurement.
I would like to freeze it or capture it and make a second spectrum measurement.
Is there a way to get both measurement on one window .

Hi Audio-Creative,

You can do this by creating a 'Reference Waveform' out of the 1st captured waveform and then capturing a second waveform (note that you can only create a reference waveform out of the transformed data, not the used display mode, if it is different to the default of 'Magnitude'). Below is the screenshot of an example.
