           EXERCISE 62 : Check the different wave shape using CRO



           Objectives

           At the end of this exercise you shall be able to
           •  identify the various controls of the function generator
           •  operate the function generator and set the required frequency and wave form
           •  measure the time and frequency of the set waveform using CRO.
           Requirements


           Tools/Equipments/Instruments
           •  30 MHz oscilloscope dual Trace    -1 Nos.
           •  Function generator                -1 Nos.

            Procedure

















           TASK 1: Identify the various controls of the function generator
           1  Write functions of function generator controls

                      Sl.no   Description                         Function
                      1       Coarse knob

                      2       Fine knob

                      3       Freq.range buttons
                      4       Duty cycle knob

                      5       INV button

                      6       Function buttons
                      7       ATTN button

                      8       SYNC terminal
                      9       DC Offset knob



           TASK 2: Operate the function generator and set the required frequency and wave form
           1  Switch ON the function generator
           2  Set the wave shape of the function generator to sine wave (refer Fig1) and record in Table 1
           3  Set the range of frequency in function generator to 10kHz
