Audio Analyzer
Oscilloscope
The scope function visualizes the waveform of the electrical in-
put signal. It automatically triggers to the fundamental frequen-
cy and selects the scaling of the X-axis (time) and Y-axis (level)
accordingly. The fundamental, or most dominant, frequency of
the input signals is displayed above the scope screen.
The scope scaling is fixed.
