The rack and power source part is a whole set, not only the electric part is a whole connection, but also the structure is connected together.

Fig.3-1 Whole structure test bench

The rack and power source part is separate. Power source part is in a standard cabinet, it is only has electric connection with rack, if without connector (cable plug or connection port), they are two separate part.

Fig.3-2 Separate structure test bench

A test bench has 1 or 2 rack; it is depend on the quantity of MUT or customer's requirement. The rack include single side or both side rack, single line or double line rack. Following is the structure of equipment (introduce as example as separate structure test bench)
