Procedure:
1. Press SAVE/RECALL SETUP ! Recall Factory Setup ! OK Confirm
Factory Init.
2. Set the vertical SCALE to 500 mV/div.
3. Set the horizontal SCALE to 10 ns/div.
4. Press TRIGGER MENU ! Mode ! Normal.
5. Press ACQUIRE ! Mode ! Average 16.
6. Connect one 50 W cable to the output of the sine wave generator. Attach a
BNC T connector to the other end of the cable. Connect a second 50 W cable
to the other side of the BNC T connector.
7. Connect the BNC T connector to CH 1; connect the cable to the EXT TRIG

13. Set the test signal amplitude for about one division on screen. Fine adjust the
generator output until the CH 1 Amplitude readout indicates the amplitude
is 500 mV. (Readout may fluctuate around 500 mV.)
14. Press TRIGGER MENU ! Slope.
