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).
