Provided are a noise floor level reduction device and a noise floor level reduction method capable of reducing a noise floor level. A transmission power measurement systemis installed before a signal measurement deviceincluding a noise floor level measurement unitthat measures a noise floor level, and a measurement unitthat subtracts the noise floor level from a level of a signal from a DUTto calculate a level of a signal after subtraction, and includes an LNAprovided between the DUTand the signal measurement devicefor amplifying the signal from the DUTand a termination resistorthat terminates an input of the LNAand the termination resistorterminates the input of the LNAin a case in which the noise floor level measurement unitmeasures the noise floor level.

Noise floor level reduction device and noise floor level reduction method

To provide a technique for simplifying a parameter setting process required to generate a test signal based on an LTE-Advanced system. Carrier arrangement designation meansdisplays a screen for selecting one of an intra-band type or an inter-band type as the arrangement of a plurality of component carriers used in an LTE-Advanced system such that one of the intra-band type or the inter-band type is designated. Parameter file designation meansdesignates a parameter file to be allocated to the component carrier among test signal generating parameter files stored in a parameter file storage meansParameter and frequency band allocation meansdesignates the component carrier to which the designated parameter file can be allocated and the allocated frequency band for communication in which the component carriers are arranged.
