Step 1

DUT / SOURCE SETUP
Ensure you have Energia IDE (software to program the MSP430 Launchpad boards) installed on your computer. 
Connect the MSP430 Launchpad board to PC using USB cable


Program it with relevant code


Take the output from mentioned probing point(s)

Step 2

EXPERIMENT SETUP
Power ON the oscilloscope
Connect the Channel 1 probe of the oscilloscope to Vout-1
Connect the Channel 2 probe to Vout-2
Acquire the signal(s) from circuit on oscilloscope

Step 3

•  Do the Autoset on the scope to efficiently capture and view the signals
If AUTOSET feature is not enabled, then manually set the horizontal and vertical scale, and trigger condition to view 3-4 cycles of waveform without any clipping.

Step 4

• Click Math button to invoke Math menu. 
• Select OPERATION = Addition (+) 
• Set sources =  CH1 + CH2

Step 5

•  You will see the Math channel (red trace) as CH1+CH2. Position and scale can be changed using MPK knob.

Step 6

ADDING MEASUREMENTS
•  Go to measurement menu by pressing MEASURE button on the scope front panel
•  Add Pk-Pk measurement for CH1, CH2 and MATH waveform from measurement menu.
•  You can navigate through the measurement list by rotating the MPK knob and select a measurement by pressing it

Step 7

• Read the measured value and verify against the expected (Math = CH1 + CH2)
