1. Connect a test circuit as depicted in figure “Test circuit”. 2. Apply an 8-scale gray signal (80 dBμV). 3. Adjust the AGC data until the output of the test circuit becomes 0.4 V (p-p) ±0.05 V. 4. Change the 8-scale gray signal to 60 dBμV. 5. The shown value of CRO should be the same as while receiving the 80 dBμV signal. If not, repeat step 3 and 4 until the results for 60 dBμVand 80 dBμV input signal are the same.
