Attention:
This product uses the local oscillator signal and the external test signal to mix to obtain the difference frequency signal, and calculates the external test signal amplitude through the detector. Local oscillator signal and external test signal are mixed to obtain difference frequency signal. This product calculates the external test signal amplitude through detector. High-precision VCO signal source can measure the heterodyne signal frequency very accurately. Due to 35M-4400M scanning range, there is no dedicated detection circuit for the external test signal, there may be errors in the measurement amplitude, so the product adds two parameters of magnification and displacement. Users can adjust displayed waveform by themselves, and adjust and calibrate displayed amplitude.
