Unformatted text preview: trend of a triangular wave. I would also assume that the signal would have some type of DC offset so that the spectrum analyzer would not be damaged. When I zoomed into the signal at 100kHz I could not see any other components to the right or left of the signal, so I do not believe that and modulation is occurring. I did not see anything at the 200kHz signal as well. Also I believe the scope was having problems because the positive spectrum should be a mirror of the negative spectrum, but there were balancing issues. This caused a problem when I tried to derive the amplitude of the signal. I decided to measure the middle of the two sides....
