And a rear panel photo. --- Quote from: Michael YYZ on October 16, 2021, 06:50:00 pm ---I have this Soviet/Russian-made school-laboratory oscilloscope which is supposed to be used as “teaching aid in high schools and radio-amateur practice”. The model is H3017 (N3017) and was manufactured in 1990. Based on a poorly translated Instructions Manual it appears to be a 100 kHz scope (amplitude non-uniformity, referenced to 1 kHz: (i) 0-100 kHz +/-30%; (ii) 100-500 kHz +/-65%). The time base and y-channel amplitude potentiometers for fine adjustments are not calibrated/graduated, so accurate voltage and frequency measurements could not be performed with this scope. Only waveform shapes can be visualized. The text-only translated Instructions Manual makes reference to block and schematic diagrams for this scope but I don’t have the original manual in Russian. I need to get a 120-230V step-up transformer before I could test the scope to see if it still works. Does anyone have information about this model? Or, would anyone have access to the original Instructions Manual in Russian, including the diagrams? Thanks! --- End quote --- |

I've just had an idea and searched for this model using Cyrillic letters instead of Latin ones - "осциллограф+н3017" - and I've got results... all in Russian. |O Luckily, Safari 15 might be able to do the job of translating. --- Quote from: Michael YYZ on October 16, 2021, 06:50:00 pm ---I have this Soviet/Russian-made school-laboratory oscilloscope which is supposed to be used as “teaching aid in high schools and radio-amateur practice”.
