Adjusting the trace position and appearance
Precautions while using Cathode Ray Oscilloscope
Adjusting the trace position and appearance
First we set the AC GND DC for both Channels A and B to GND.this should allow us to see a horizontal line across the display The next thing that we do is use the Mode Selector to allow us to view channel A on the display.Now that we can see the position of the trace we use both the Intensity and Focus controls to achieve a clear appearing trace.Finally we move the trace into the center of the display using the both the Horizontal Position Control and the Vertical Position Control corresponding to Channel A.Use the Mode Selector to view the trace of Channel B on the display.Repeat d .Finally to check that the above steps have been carried out correctly we can set the Mode Selection Switch to DUAL which will allow us to view both traces on the displays.s
