As you select each frequency measurement, on screen help will appear to explain the purpose of that measurement. A
Con fi gure item will appear on the lower menu. After you press Con fi gure and set the measurement parameters in the
resulting side menu, the oscilloscope will automatically set the span. When the RF measurements are on, the Auto detection
method will set all frequency domain traces to the
Average detection method. This provides optimal measurement accuracy.
