Scared of all the controls and numbers of a cathode ray oscillator? Do not be afraid! It is not that difficult to use after learning the basic functions.
Step 1. Make sure the intensity is low before turning on the oscilloscope
Step 2. Turn it on
Step 3. Wait for the valve to warm up and start working
Step 4. Increase the intensity until you get a horizontal line that is not too intense
Step 5. Adjust the focus to make the line as thin as possible
Step 6. Connect a probe to the CH1 input
Step 7. Connect the other end to the CAL output
Step 8. Adjust the time and amplitude (for CH1) until you get a square wave that takes up most of the screen and shows at least one full cycle
Step 9. Adjust the probe so that there is no overshoot or undershoot
Step 10. Remove the probe tip from the square wave output
Step 11. You are now ready to use the oscilloscope to measure all waveforms
Step 12. The tempo control provides a horizontal display while the amplitude provides a vertical display
- You will need to adjust the trigger level if the trigger LED light does not turn on or if you cannot see any waveforms when the probe is connected.
- If you don't see the horizontal line when the probe is disconnected, try adjusting the position of the controls.
