Sl. No Selected Set Set Volt/div Measured Set Time/ Measured Frequency
waveform frequency on CRO Vp in CRO div on time period (1/T)
in Function CRO (Time/div x
generator division for 1
cycle)

TASK 3: Measure the time and frequency of the set waveform using CRO

1 Switch ON the CRO
2 Connect BNC cable to CRO and calibrate the CRO by adjusting the Time/div and volt/div and other measuring
conditions.

3 Connect the function Generator output to CRO input as in Fig 2

Fig 2

4 Adjust the trace on the center of CRO
5 Set the volt/div and time/div of the CRO to properly display the waveform in CRO and adjust amplitude in
function generator (refer Fig 3)
