Not knowing your specific application I have to ask - Phase noise or jitter? Jitter and phase noise are essentially Time and Frequency domain representations of the same thing. Most jitter measuring equipment, mostly oscilloscopes, can convert to phase noise, or you can calculate it from the data. -- Mark Randol, Lab Guy ON Semiconductor 901 S Mopac Expy Barton Oaks 4, Ste 343 Austin, TX 78746-5929 512-329-5640 (V) 512-329-8151 (F) -----Original Message----- From: si-list-bounce@xxxxxxxxxxxxx [mailto:si-list-bounce@xxxxxxxxxxxxx] On Behalf Of nagar ashish Sent: Thursday, November 07, 2013 4:56 AM To: si-list@xxxxxxxxxxxxx Subject: [SI-LIST] Phase Noise Measurment Hi, We have requirements of measuring Phase Noise of multi port PLLs (100 Pcs in a weeks time). Do any of you have suggestion on measurement technique ? Although we have one Phase Noise measurement equipment but it has only one channel. I am looking for multi channel equipment or any other out of box suggestion to quickly measure Phase noise Regards Ashish ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List forum is accessible at: http://tech.groups.yahoo.com/group/si-list List archives are viewable at: //www.freelists.org/archives/si-list Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List forum is accessible at: http://tech.groups.yahoo.com/group/si-list List archives are viewable at: //www.freelists.org/archives/si-list Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
