PEPS (Passive Entry & Passive Start) product radio frequency calibrating system

The utility model relates to the PEPS (Passive Entry & Passive Start) technical field, in particular to the PEPS product radio frequency calibrating system used for calibrating the LF (low frequency) radio frequency signal strength at a PEPS base station. The calibrating system comprises a PEPS base station, an LF signal testing device, an RSSI (Received Signal Strength Indicator) data receiving module and a data processing system; the LF signal testing device comprises a 3D (Three Dimensional) low frequency antenna, an RSSI module, an A/D (Analog / Digital) conversion module and a UHF (Ultra High Frequency) module I, the RSSI module is used for obtaining the received signal strength data of the 3D low frequency antenna, the data is converted by the A/D conversion module and then transmitted through the UHF module I; the RSSI data receiving module comprises a UHF module II and is used for receiving the received signal strength data transmitted by the LF signal testing device and transmitting the data to the data processing system. Furthermore, the data processing system is a PC (Personal Computer) and the LF signal testing device is an intelligent key.
