| 摘要 |
Phase noise analyzing system that analyzes phase noise in radio frequency (RF) signals provided by a device under test when coupled thereto includes a low noise receiver that receives at a first input, signal from the device under test when coupled thereto, a low noise synthesizer that provides output to the receiver, a frequency domain analyzer that receives output from the receiver, a time domain analyzer that receives output from the receiver, a switching system that controls signal flow to and from the receiver, the synthesizer, the frequency domain analyzer and the time domain analyzer, and a computer that controls the switching system to perform the analysis of phase noise in signals provided by the device under test. |

1. A phase noise analyzing system that analyzes phase noise in radio frequency (RF) signals provided by a device under test when coupled thereto, comprising:
a low noise receiver that receives at a first input, signals from the device under test when coupled thereto, said receiver including a phase lock loop, and compensation means for compensating for a suppression effect induced on phase noise by the phase lock loop; a low noise synthesizer that provides output to said receiver; a frequency domain analyzer that receives output from said receiver; a time domain analyzer that receives output from said receiver; a switching system that controls signal flow to and from said receiver, said synthesizer, said frequency domain analyzer and said time domain analyzer; and a computer that controls said switching system to perform the analysis of phase noise in signals provided by the device under test. |
