Abstract
PURPOSE:To easily obtain a high frequency variable phase signal with good accuracy and stability, by generating a stable variable phase signal with high accuracy, in the low frequency area, then making frequency conversion to obtain a high frequency variable phase signal and adjusting the phase in the low frequency. CONSTITUTION:A signal of frequency fL is generated by the low frequency oscillator 1, and a part of its output is supplied to the frquency mixer 5 as a low frequency reference phase signal. Also, a part of said output is supplied to the low frequency phase shifter, its phase is adjusted, and it is supplied to the frequency mixer 4 as a low frequency variable phase signal. On the other hand, a signal of frequency fH is generated by the high frequency oscillator 3, and its output is supplied to the frequency mixers 4, 5. A signal containing each frequency component of fH-fL, fH, fH+fL is output from these frequency mixers 4, 5.
