4. Increase the frequency to 60 MHz (for 100-MHz instruments), or 150 MHz (for
200-MHz instruments). To enter 60 MHz, press 60MH; then press
E .
5. Continue to increase the frequency slowly until the waveform decreases to 4.2
divisions, as shown below.
To increase the frequency slowly, fine-tune it using the rotary knob, To do this, press
e to place a cursor in the Output Display. Press e again to place it in the
frequency field, and use the L and W keys to move it to the digit you want to
change. Then change the value by turning the rotary knob.
Continue making small increments in the frequency until the signal drops to 4.2
divisions. At 4.2 divisions, the signal is at the frequency that corresponds to the
-3 dB point.

6. Remove the input signal by pressing Y.
7. Repeat this procedure for the remaining channels on your oscilloscope.
