Zusammenfassung:	PURPOSE: An expandable passive inter-modulation analysis apparatus is provided to record changes of calibration information which is stored in a sub rack by transmitting the changes to a memory of a main rack, thereby simplifying repair tasks by separating the sub rack of a corresponding bandwidth. CONSTITUTION: An expandable passive inter-modulation(PIM) analysis apparatus is comprised of a PC(10), a main rack(20), and a plurality of sub racks(30). The PC commands a band selection process of the main rack in order to select a measurement bandwidth. An operation program for measuring PIM of a selected band is installed in the PC. The main rack is connected to the PC in order to communicate in a one-to-one mode with the PC. The plurality of sub racks is respectively controlled according to the selected band. The plurality of sub racks is connected to the main rack in order to communicate in a one-to-n mode with the main rack. The sub rack measures the PIM with respect to a distinct bandwidth and transmits a measured value to the main rack.
