How do I Calculate the Ratio of Two Voltages in Decibels Using the DLM2000 Mixed Signal Oscilloscope User-Defined Math?
Resources:
For the DLM2000 Mixed Signal Oscilloscope with user-defined math (G2 Option), you can calculate the ratio of two voltages in decibels. The formula for calculating the ratio of two voltages in dB is:
dB = 20*Log(Voltage1/Voltage2)
Follow the procedures listed below to perform the calculation:
- Press MATH/REF » Mode » Math1 soft buttons to select CH1 math
- Press Operation » User Define soft buttons to set the operation to user defined math
- Press Expression soft button and enter the formula:
20*LOG(P.RMS(C1)/P.RMS(C2)) - Press Enter to confirm the expression
Please view the attached file for an example screenshot and the calculation result.
