Let me leave a brief note about "frequency response analyser" of Moku:Lab, especially the definition of the vertical axis of the upper panel (see this screen shot).

Since it uses a unit dB, sometime I'm (and someone should have been) confused if this means in power or amplitude; as a conclusion, it means power.

To confirm this I used 1st-order low pass filter in SR560 with cutoff of 100 kHz as a reference. The screen shot is the measured transfer function of that. 

At 100 kHz, you see the decrease of gain by -3 dB. This means:-3 dB loss in power (=in Moku:Lab) corresponds to *1/sqrt(2) in amplitude.

More generally if the output gain of Moku is G dB, the amplitude gain g in log-scale should be calculated as:

g = 10**(G/20)

Ex.) -20 dB in Moku:Lab corresponds to 1/10 in amplitude.
