CF-5200 Frequently Asked Questions
Question number FAQ-0545
The relationship between the dB/V values when the Y-axis is switched between Log/LIN is as follows:
If Vr is the Y-axis LIN value (effective value) at a certain frequency, and Y is the dB value at that time,
Y (dB) = 10Log (Vr/A) 2
A = Amplitude RMS value 1Vr
(The values are expressed by taking the logarithm of the scale relative to 1Vr.)
