If your project contains an array of line objects, you can also define an array of '''Lumped Sources''' to be placed on those lines. If you insert a new lumped source, all line array objects, if any, will be listed in the Lumped Source dialog as eligible objects for lumped source placement. A lumped source will be placed on each element of the array. All the lumped sources will have identical direction and offset. However, you can prescribe certain amplitude and/or phase distribution among the array elements. The available '''Weight Distributions''' include '''Uniform''', '''Binomial''', '''Chebyshev''' and '''Data File'''. In the last case, you need to set a value for maximum side lobe level ('''SLL''') in dB. You can also define a '''Phase Progression''' in degrees along each of the three principal axes.
