Example: Signal Sum
This program (found in the “Examples\chapter6\Signal Sum Example” subdirectory on
the CD-ROM) configures a pulse waveform with duty cycle, which is then slowly
modulated by a triangle waveform.

'Signal SUM Example is a sample program to demonstate the capablity of adding two
Channels function and get the output
'
'Algorithm:
' 1. Set the base signals to sum on Channel1 & Channel2.
' 2. Set the SUM modulation on Channel 1.
' 3. Source for SUM modulation will be Channel2 function.
' 4. Set Sum Amplitude.
' 4. Enable modulation output.
' 5. Enable channels output.
' 6. For Verification, we can route the signal to oscilloscope and see the result.
'
'Channel 1 Parameters:
' Wave Shape: Sine
' Frequency: 1000 Hz
' Amplitude: 2 Volt Peak to Peak
' Offset: 0 Volt
' Output Impedence: 50 Ohm
'
'Channel 2 Parameters:
' Wave Shape: Square
' Frequency: 1000 Hz
