There is no doubt that the oscilloscope is one of the most useful instruments in the electronics studio. It allows you to visualize voltage waveforms in time, which is extremely useful when tuning, testing and servicing various types of electronic devices.
The performance of the presented oscilloscope will not ruin the budget of not-so-rich electronics and will allow it to take advantage of all the advantages that this type of equipment possesses.
The oscilloscope was designed as a PC computer adapter. The software was written in Delhi and can be easily modified. Voltage measurement is carried out using an ADC 'converter supported by FIFO memory. The use of the latter eliminates the need for high-speed meter systems, bus multiplexers, etc., which translated into a significant simplification of the board and software (and consequently low overall price).

The device is particularly recommended in the electronics workshop, especially the beginner
