X-Deflection broken on C1-5 oscilloscope?

I recently acquired a C1-5 soviet-made oscilloscope in unknown condition that has been sitting in a workshop for 18 years. I was not able to find a manual. When turning it on (y-input and x-input disconnected) a single dot appears on the screen.…

Wheatstone bridge to create offset

While comparing schematics of two old analog oscilloscopes (Tektronix 475 and Goldstar 9020,) I was expecting many differences to get better frequency response since the first is a 250MHz and the second is only 20MHz. My question here is about the…

Questions on hooking up an old cathode ray tube (CRT)

I bought an 8LO29I Soviet era CRT (intended for use in oscilloscope/instrumentation): Now I'd like to get it to work. After almost endless reading up (I'm not an electrical engineer) I think I now know what to do. The CRT also came with extensive…

Tektronix 453 - Time/Div dial has no effect

I recently picked up a Tektronix 453 Oscilloscope and it works pretty much flawlessly, but turning the time/div dial (the clear plastic flange) does nothing to the display. I tried hooking up CH 1 and CH 2 to the 1 kHz calibration signal, and about…

Parts for Cathode Ray Oscilloscope

I am building a CRO. I made a circuit for it but I am not able to figure out which parts to use. Can anyone suggest low noise high frequency (at least 1 MHz unity gain) op amp which can give at least 15 mA output ? Also I am finding IC capable of…

Phase difference from Lissajous figure of 8 in a CRO for which frequency relation is twice

For the below figure of 8 Lissajous pattern, it is clear that the frequency of the Y input is half the X input. However how to conclude about the phase difference relation. The answer is option D, is it because the sense of direction is clockwise?…
