摘要：For example, a preselector for preventing an image signal from being inputtedis omitted from a spectrum analyzer, and thereby the image signal out of the presetmeasurement frequency range can be suppressed. Intermediate frequencies Fi are set ina preset measurement frequency range from F1 to F2. The frequency section of thesweep signal from F1+Fi to F2+Fi is swept to determine first measurement data, and thefrequency section from F1-Fi to F2-Fi is swept to determine second measurement data.The first and second measurement data are compared with each other for eachmeasurement frequency point. If they agree with each other, the data is outputted;otherwise a minimum data value is outputted. Thus, measurement data is obtained whileimage data based on the image signal is suppressed.
