Test Record From - Rigol DHO4000 Series Performance Verification Manual

8. Calculate the amplitude loss with the following formula: Amplitude Loss (dB) = 20
x lg (Vrms2/Vrms1).
9. Repeat Step 2-7. Measure Vrms1 and Vrms2, and calculate the amplitude loss of
500 mV/div vertical scale.
10. Turn off CH1. Measure CH2, CH3, and CH4 respectively using the method above
and record the measurement results.
