9. True rms voltage (Vrms ac+dc)
The surface of the AC and DC component is
calculated and converted into a Rms voltage
value.
10. dBV AC+DC measured
The recorded AC signal and the DC compo-
nent are converted to dBV (0dB=1V)
11. dBm AC+DC measured
The recorded AC signal and DC component
are converted to dBm (0dB=0.775V)
12. dB AC+DC measured
The recorded AC signal and the DC compo-
nent are converted to dB (0dB=dBref*)
13 *dBref
Select dBref to set the reference level for dB
measures defined by the user. The chosen
readouts will be set on dB.
Calculating audio power:
The measured voltage is converted to power,
taking consideration with the fact that the
voltage is measured over certain impedance.
The calculated power can be shown for loads
of 2, 4, 8, 16 or 32 ohms. To choose a load,
select the power readout and move the joy-
stick to the right.
