Make an appraisal of modulators.
In Dipol's Lab we have carried out comparative measurements of the modulator Signal Digital Classic R95175
, and another one, of a brand from the market. The pictures below show the results that have been seen on a spectrum analyzer's screen. On the left from the dotted line you can see spectral lines of modulated signals. On the right from the dotted line there are seen unwanted harmonics of the useful signal. The modulator Signal Digital Classic R95175
generates them at considerably lower level, so that inserts lower distortions that might interfere with other channels.
