Summary:This device solves the problem that the complicate channel analog apparatus (CCAA) suits only a smaller input signal level change range and a smaller total link loss change range during the channel analog. The mentioned CCAA consists of the control unit, the 1st signal level regulator (SLR), the up-going CCAA and the 2nd SLR. The control unit is used to define the gains of the 1st and the 2nd SLR. The 1st SLR is used to regulate the terminal emitting signal level according to the gain of the 1st SLR and sends the terminal emitting signal to the up-going CCAA. The 2nd SLR is used to regulate the terminal emitting signal level according to the gain of the 2nd SLR and sends the terminal emitting signal to the base station. This invention also discloses a channel analog system and a channel analog method. They can be used in the channel analog of the signal level with a rather big link loss range.
