Any audio editor will generate a digital "square wave". Some are free, others have free trial downloads. This will take care of the "digital signal generator" portion.
You can also use a sound card to capture an analog signal, e.g. the output of a DAC. You can then use an audio editor to plot the resulting waveform.
