6.11 Capture and Output Math Waveform
This section will demonstrate an example of capturing a Math
waveform output that is internally calculated between two
channels of the oscilloscope and storing it into arbitrary
waveform memory for output from the generator. In this
example, CH1 and CH2 signals will be added together to
create the Math waveform.
Follow the steps below:
1. Press the MATH key to enter the MATH menu, and
set Operate parameter to A+B.
