Level Measurement
The Level menu features three different measurement selections to
choose from:
• Level peak
• Level RMS
• Level sweep
Level peak measurements indicate – thought digitally – the maximum
number (value) of the input signal.
Level RMS measures the power of the signal. The RMS functions of
the Digilyzer such as Level RMS, sweep and THD+N are available
as single channel functions only.

Measurement Functions
Application hint:
In digital audio the level peak measurement is basically mostly used,
while in the analog area RMS values are important. Whenever you
want to make measurements in the area of “frequency response”,
RMS is usually the correct choice.
