This shows the benefit of an analog CRO in XY mode.
The signal is the demodulated IQ pair from a phase analysis light scattering (PALS) apparatus. The amplitude and phase determined by the composite signal of light scattered by nanoparticles in a liquid. Random diffusion causes random fluctuation in both the amplitude and phase. Hence, the oscilloscope is very useful in visualizing this diffusion in real-time. Application of an electric field causes charged particles to move linearly. This manifests as a Doppler shift that is seen as rotation of the signal on the oscilloscope. The beeps correspond to when the field is turned on and off.
Trying to view this on a DSO such as a Rigol DS1104Z isn't even worth the effort...
