A transmitter upconverts a SSB data signal during a first operational mode using a RF upconverting signal having a frequency that is offset from a center frequency of a channel by an amount that depends on the data signal’s SSB bandwidth. The device includes a QoS calculating unit for calculating response performance and analysis accuracy when executing an analysis process in the media analysis system by preset media data input method and analysis method, based on the stored analysis characteristics information and media characteristics information. The foot member is installed through the opening of the slider. In an enhanced embodiment, the system is tested by substituting an inject-fault-data entry of the inject-fault-data table for a control-data entry of the control-data table as an input to the system. The correction width is also determined in accordance with a change in environmental temperature. The computer has previously stored data on the inventory of consumables in each medical institution, and determines the quantity of consumables consumed in each medical institution based on the operation status data that are received, updates the consumables inventory data, and if necessary, carries out the procedures for supplying an appropriate quantity of consumables.
