摘要： To provide a quadrature modulator, a signal generating device, and a quadrature modulation method capable of correcting a gain balance error, a zero offset error, and an orthogonality error that occur during quadrature modulation. The quadrature modulator 20 includes a quadrature modulation unit 22, a quadrature modulation error calculating unit 40 that calculates quadrature modulation errors on the basis of the power of a quadrature-modulated signal output from the quadrature modulation unit 22, and an error correcting unit 30 that corrects a baseband signal such that the quadrature modulation errors are removed. The quadrature modulation error calculating unit 40 includes a power measuring unit 41 that measures the power of the quadrature-modulated signal, a gain balance error calculating unit 42, a zero offset error calculating unit 43, and an orthogonality error calculating unit 44.

摘要： A signal generator has a signal creating and supplying unit which creates a test signal to be transmitted to a measurement object and a license management unit which manages a license of waveform data for use in creating the test signal by the signal creating and supplying unit. The license management unit includes a waveform data memory which stores a plurality of waveform data files, a usable file list taking unit which takes a usable file list for specifying a usable waveform data file authenticated for the signal generator, the usable file list being input from an outside section, a usable file list memory which stores the usable file list, a determining unit which determines whether or not a desired waveform data file is included in the usable file list stored in the usable file list memory, and a waveform data file reading and transferring unit which reads the specified waveform data file from the waveform data memory and transfers the specified waveform data file to the signal creating and supplying unit when the determining unit determines in the affirmative.
