D&B D80 - Signal Scope for Monitoring; Signal Monitoring and Application Examples

9.5.5. Scope
The «Scope» function allows basic signal monitoring of the
amplifier's output voltage (full color) and output current (light
color).
Select
A U, I Output voltage and current of channel A.
B U, I Output voltage and current of channel B.
C U, I Output voltage and current of channel C.
D U, I Output voltage and current of channel D.
All U Output voltage of all channels.
All I Output current of all channels.
All U, I Output voltage and current of all channels.
Y scale
Scale of the measuring values in FS (Full Scale). 1.0 FS represents
the maximum output voltage or output current.
Application examples
The scope function is a useful tool for ...:
– determining the signal quality.
– determining a phase shift between the channels.
– getting a rough impression of the crest factor.
– checking the output channels (e.g. no output current
displayed Þ the connector cable may be interrupted or
no loudspeaker is connected.
– checking the power amplifier (e.g. no output voltage
displayed).
