15. dBm measurement (dBm ac+dc).
The measured signal (ac+dc) is converted to
dBm (0dBm=0.775V).
16. dBG measurement (dBG ac+dc).
The gain between channels 1 and 2.
(excludes dc).
If we measure the amplification on channel 2,
the relation will be:
• Channel 1: input signal
• Channel 2: output signal

17. dB measurement (dB ac+dc).
The measured signal (ac+dc) is converted to
dB (0dB=dBref).

18. ac+dc power
AC+DC power calculation into selected impe-

17
DC component).

Audio power calculation.
The measured voltage is converted into

supposing
measured
calculated power can be displayed for loads
of 2, 4, 8, 16 or 32 Ohm. To choose the
different loads, first highlight the power
