We are using E5052B to measure the output phase noise of a DDS module. At 300.01MHz output the measured Phase Noise at 10 KHz offset is -142dBc/Hz. However, when I configure the DDS module for 300MHz Output, phase noise will increase to -130dBc/Hz (12dB Difference). The only difference between these two tones is several near-carrier spurs (less

Key parameters of PCB materials, such as DK, TanD, dielectric height, etched trace width, copper thickness and roughness, are critical for high speed PCB transmission line design. In this mini workshop, Beatty series resonant impedance structures are used to improve accuracy of PCB material property extraction for EM simulation and signal
