Scope

This is an audio bandwidth oscilloscope. This function provides an accurate graphic representation
of audio waveforms, allowing users to better identify audio distortion, clipping, and problems with the
polarity of a signal.
Using the scope to measure a waveform:
1. Enter the SET menu within the Scope function (figure 52). Here users can adjust the input source,
unit, response time and trigger. The scope can be used for a multitude of measurements, both
through the mic and line inputs.
2. Set the range of measurements taken. The range can depend on the 'unit' selected in point 1. In dB
SPL, users can select 30 to 100 dB SPL, 45 to 115 dB SPL or 60 to 130 dB SPL. When operating
under dBu, the range can be adjusted between -85 to -20 dBu, -75 to -5 dBu, -60 to 10 dBu and -45
to 25 dBu. When dBV is selected as the unit, the range is selectable between -87.2 to -22.2 dBV,
-77.2 to -7.2 dBV, -62.2 to 7.8 dBV and -47.2 to 22.8 dBV. Under voltage, users can select 43.6u
to 77.4mV, 0.14m to 435 mV, 0.78 to 2.45V or 4.36m to 13.7V.
