NettetThe noise power ratio (NPR) is a classical metric that can be measured without high-rate ADCs. The third measurement method, called the error power ratio (EPR), shows that … NettetAlthough its amplitude has been remarkably decreased by angle polishing, residual backreflection noise is still a severe factor in RIOGs. Next, a hybrid phase-modulation method to eliminate the backreflection noise is constructed, and the frequency spectra of the photodetector outputs before and after adopting HPMT are analyzed.

NettetIn a similar manner, integrated phase noise integrates the noise power at different offsets from the carrier and expresses this noise as a dBc number compared to the output frequency. ADIsimPLL can be configured to calculate the EVM, integrated phase noise, and rms phase error and jitter. Nettetphase noise and buffer’s noise floor dominate. Setting the loop bandwidth appropriately with respect to the input phase noise is always complicated. The phase noise of the VCO gets noisier close to carrier frequency. Selecting a lower loop bandwidth means that overall the PLL output is more dependent on VCO phase noise closer to the carrier ...
