Precautions while using Cathode Ray Oscilloscope
I. Set the signal generator to a frequency of 1000 cycles per second. Connect the output from the gererator to the vertical input of the oscilloscope. Establish a steady trace of this input signal on the scope. Adjust play with all of the scope and signal generator controls until you become familiar with the functionof each. The purpose fo such playing is to allow the student to become so familiar with the oscilloscope that it becomes an aid tool in making measurements in other experiments and not as a formidable obstacle. Note If the vertical gain is set too low, it may not be possible to obtain a steady trace.
