OPD602 slow-action oscilloscope

Slow-action oscilloscopes were useful in healthcare (for EKG and EEG measurements), but also in machine and construction industry for measurements of resonant frequencies of structures, for combustion engine development etc. The OPD oscilloscopes, manufactured by Tesla Valašské Meziříčí, could be equipped with various plugin cards, such as digital storage of signals, selective amplifiers, electronic component testers etc. The oscilloscopes could be connected to a separate monitor, e. g. if used in a hospital - the oscilloscope would be placed next to a patient to measure their EKG and a separate monitor would be used in the nurse's room. More patients could be monitored at once and an alarm would be triggered in case of an emergency.
