  Each measuring device is connected to a plurality of wireless communication antennas of the terminal device via a measurement cable or a shield box. In the normal line system, thousands of terminal devices are produced per day, so the inspection time that can be applied to one device is very limited, and efficient measurement in a short time is required. The time required for inspection per terminal device generally differs depending on the communication standard. However, a measurement system that can perform measurement efficiently while keeping the speed of the belt conveyor constant is desired.

  On the other hand, the cell method is a manufacturing method suitable for the production of a variety of terminal devices in a smaller amount than the line method, and is generally performed in a small-scale manufacturing factory. In the inspection in the cell system, measurement of all communication standards supported by the terminal device to be measured is performed for each terminal device by a measuring device having a general-purpose signal generation function and signal analysis function that does not depend on the communication standard. Done.
