Set up channel 1 to show the RF. The probe just goes across the dummy load.
Set for 5 v/div, and adjust power/gain to see a nice size.
Set up channel 2 to show the keyer (external keyer ideal, internal keyer use
positive trigger and 8T on the AUX IO port or somewhere internal). Set the
trigger for negative going up around 3 volts (it'll go off when the dot line
goes from 5v to 0v and precede any RF).
Set up the sweep rate to show both the rise and fall. For 50 WPM dits, 5
mS/div will be nice (and 1 div is your target rise/fall time).
