The video shows a person using a Rigol DS1052E oscilloscope to measure the frequency of a signal. The oscilloscope has a digital display and several buttons and knobs on the front panel. The person is using their hand to adjust the settings on the oscilloscope, which is connected to a black wire. The display on the oscilloscope shows a waveform with peaks and valleys, indicating the amplitude of the signal over time. The person's hand is visible in the frame, and they appear to be wearing a red sweater. The background is blurred, but it seems to be a workshop or lab environment with various tools and equipment.
