Signal spectra
In this experiment the relationship between time- and frequency domain of different signals is examined.
You can choose from a variety of source signals. For example, let's select a rectangular waveform with 1mV amplitude and a frequency of 1kHz.

The selected signal can be viewed in the oscilloscope (time domain) and spectrum analyzer (frequency domain).

If needed, you could change the scaling on every measuring instrument by clicking on the little gearwheel on the upper right to gain a better view on the signals.

Can you consider which spectrum a triangle shaped source signal generates?
Let's see.
