Testing Phase Noise of
Ultra Low Phase Noise OCXOs
Challenges and Solutions
|
 |
 |
Cross correlation technique is used
to test phase noise of ULPN OCXOs
Four test instruments are evaluated:
|
• Noise XT DCNTS
• Agilent’s E5052B
|
• Symetricomm 5120A-01
• Anapico APPH6000
|
Each is rated in terms of:
|
• Accuracy
• Speed
• Ease of use
|
• Range
• Cost
• Ease of data retrieval
|
