Oscilloscope Analysis (Audio Spectrum Analysis Screen)
The SPECT button (in the audio panel) switches the display to the Audio Spectrum
Analysis Screen. This is an oscilloscope-style display of the input waveform. It allows
visual inspection of received audio and can be helpful when identifying video and digital
transmissions. In this mode, high frequency, digital signals may have very little signal
level due to the limited sampling frequency of the OSCOR microprocessor.
To enter the Audio Spectrum Analysis Screen, press the SPECT button.
To configure the Audio Spectrum Analysis Screen:
1. In the Audio Spectrum Analysis Mode, press the MENU button (labeled CONFIG).
2. Press F1 to toggle the Peak Audio Level Display mode.
3. Press F2 to toggle the trigger mode. The trigger mode is similar to the trigger
control on an oscilloscope.
4. Press F3 AND F4 to control the trigger level setting. This allows the user to adjust
the automatic triggering function. The F3 and F4 button should be held down and
the dashed line on the screen shows the triggering level.
5. Use the EXPAND/NARROW buttons to control the time spectrum of the display.
6. Use the UP/DOWN buttons to control the vertical display size.
