Test the lower bandwidth trigger sensitivity.
aa Use the RPG knob to dial in s/Div of 20 ns.
bb Set the signal generator to provide a 50 MHz signal with 35 mV rms amplitude.
cc Press the blue shift key, then press the Run key.
dd If the oscilloscope doesn’t trigger, move the cursor to the Level field and use the RPG
