Amazing old school electromechanical ramp generator
ChristofferB:
It's not repetitive, making the lack of a trigger input even weirder.
It's been driving a current source for some magnetic coils in a superconducting magnet setup. Sweeping the magnetic field allows for stuff like MRI, NMR and electron paramagnetic resonance.
Today you would scan many times and average out the noise, back then youd do one slow scan to avoid artifacts. The sweep out would also be the X axis of a 2D pen plotted.
