Currently the spectrum analyser measurements are very difficult to read because they are so small and jump around as the display is updated . It's almost unusable . If they could be displayed in large text in the Multimeter display that would be perfect , because then they could be seen from a distance and it would not be necessary to see the Spectrum or Oscilloscope displays to read their parameters .
You can adjust the font size through [Setting]>[Display]>"Font Size". Another way is to use the DDP Viewer which will display a Derived Data Point, such as peak frequency, RMS value, etc., in a separate window with adjustable size.
