What is an effect of excessive phase noise in an SDR receiver’s master clock oscillator?
It limits the receiver’s ability to receive strong signals
It can affect the receiver’s frequency calibration
It decreases the receiver’s third-order intercept point
It can combine with strong signals on nearby frequencies to generate interference✓Correct answer
Explanation
Phase noise on the master clock spreads energy either side of the nominal frequency, and a strong signal on a nearby frequency mixes with those sidebands and is translated into the passband as noise-like interference. The effect degrades reception of weak signals near strong ones, rather than limiting strong-signal handling or upsetting frequency calibration.
