<character_data>,<character_data>[,<numeric_value>]
This command sets the source for the common mode operation. The common
mode operation adds two sources and divides the resultant by two. It is done
point by point.
– If the source(s) input is in the log scale, it will be converted to the linear scale
NOTE
– If the trace length between the channels is not equal, the waveform math
– If the number of trace points is not equal, the waveform math operation will

traces to an equal length.
