1. A measuring device comprising:
a receiver configured to receive a signal to be measured transmitted from a mobile terminal;
a processor configured to
convert the signal to be measured into a digital signal and calculates signal data;
output a trigger signal at a predetermined timing when a predetermined trigger condition is satisfied, wherein the predetermined trigger condition includes a detection of a preset physical layer level channel, a preset control information, or a preset reception status from the received signal;
receive the trigger signal, and extract IQ data in a predetermined section according to the predetermined timing from the signal data; and
an IQ data analysis processor configured to analyze the extracted IQ data, wherein
the signal data extracted by the processor is signal data of a physical layer, and the trigger signal is output when the predetermined trigger condition is either uplink shared channel (ULSCH), uplink control information (UCI) (scheduling request (SR), Channel State Information (CSI), or hybrid automatic repeat request-acknowledgement (HARQ-ACK)), physical random access channel (PRACH) or sounding reference signal (SRS), a total received power is equal to or higher than a predetermined threshold, and the preset reception status is discontinuous transmission (DTX), cyclic redundancy check (CRC) NG, CRC OK, Decode NG, or Decode OK.
