Abstract:
The signal analysis device includes a synchronization data generation unit 19a that outputs an A/D-converted correction signal as first synchronization data which is associated with time based on the timing of a trigger signal input from the outside, a synchronization correction value calculation unit 19c that calculates, as a first synchronization correction value, an amplitude ratio, a phase difference, and a time difference between the first synchronization data and second synchronization data input from the outside on the basis of the first synchronization data and the second synchronization data, and a correction unit 19d that corrects the amplitude, phase, and timing of the RF signal output from the object to be measured, on the basis of the first synchronization correction value or a second synchronization correction value input from the outside.
