The ADD command adds values of source
1
and source 2 (point by point), and sends the sum to
the destination.
Traces, user-defined traces, and trace ranges are added as 16-bit integers. Negative numbers
are represented in two’s complement format. Single variables and numbers are treated as
floating point numbers and must be within the real number range as defined in
Table
5-1.
The sources and destination may be different lengths. The length of predefined traces (trace A,
trace B, or trace C) is 401. User-defined traces have a length of up to 2047, and variables have
a length of 1. When sources differ in length, the last element of the shorter source is repeated
for the addition process. After the addition, the last element is repeated if the destination
is longer than the sum trace. When the sources are longer than the destination, they are
truncated to fit.
