5.2. How to program an Arduino
...
6.8.1. Connect a second probe to the digital pin 8 as done before (pin 7 remains connected to the first probe!).
6.8.2. Now switch the trigger source to pin 8 (if pin 8 is connected to input 2, a “2” should be selected as the trigger source) and trigger the signal.
6.8.3. Activate the “Math” function by pressing the transparent knob on the bottom left of the control panel (purple in the picture of the front panel above).
6.8.4. Select “-” as the operator you want to use to highlight areas where the signals from pin 7 and pin 8 are different. If everything is set up correctly you should see two rectangles of the same size (see below).
...
6.10.4. Set up the trigger to display the UART signal coming from the Arduino (Pin 1 labeled as“1<-TX”).
If everything is set up correctly, you should get a similar view as below, if you don’t, try to set the vertical and horizontal zoom to the same as in the picture (top row above the table in the picture):
