7. True RMS readout (Vrms ac)
The surface of the AC wave is calculated and
converted to a voltage (True RMS).
8. dBV measurement (dBV ac).
The measured signal (ac only) is converted to
13
dBV (0dBV= 1V).
9. dBm measurement (dBm ac).
The measured signal (ac only) is converted to
14
dBm (0dBm= 0.775V).
10. dB measurement (dB ac).
The measured signal (ac only) is converted to
dB (0dB= dBref).
11. dBG measurement (dBG ac).
The gain between channels 1 & 2.

If we measure the gain on channel 1, the
relation will be:

12. Power (Wac) (AC only)
AC Rms power calculation into selected impe-
dance
13. True RMS readout (V ac+dc)
The surface of the waveform (AC+DC) is
calculated and converted to a voltage (True
RMS).
14. dBV measurement (dBV ac+dc).
The measured signal (ac+dc) is converted to
dBv (0dBV= 1V).
• Channel 1: output signal
• Channel 2: input signal
