ABSTRACT:
A novel vector signal generator is provided which includes a vector modulator controlled by baseband manipulation circuitry. The output signal from the vector modulator is down converted to a desired output frequency. The baseband manipulation circuitry provides, under digital control from, for example, a microprocessor, adjustments to the phase, carrier leakage, and modulation levels of the I and Q signals. In this manner, a highly accurate vector modulated signal is generated within a wide range of carrier frequencies.
