Hi Henk:Here is a spectrum plot from my PRS10. But it's also connected to the SR620 so I'm not sure where the spurs are coming from.
Have Fun, Brooke Clarke http://www.PRC68.com http://www.pacificsites.com/~brooke/PRC68COM.shtml http://www.precisionclock.com Henk ten Pierick wrote:
Hi Said, Thanks for the picture.I have inserted a 100MHz lowpass between the PRS10 and the Wavecrest tot remove the spurious signals. There is a large difference in phase noise close to the carrier as calculated by the Wavecrest. It is unclear to me if the spurious is normal or not. The spurious of my PRS10 is 60dB down the 10MHz so it is strange that you see no spurious.Henk ------------------------------------------------------------------------ On Apr 24, 2007, at 20:18, [EMAIL PROTECTED] wrote:In a message dated 4/23/2007 10:51:38 Pacific Daylight Time, [EMAIL PROTECTED] writes:Your picture's input level is 5dBm. The SRS spec for PRS10 is 7dBm output. Were is the difference?Did you measure wideband spectrum of the PRS10 output? Up to 1GHz?retry: the attachement was too big first time I tried sending this: Hi Henk,I measured my PRS-10 tonight on an 8563E, you can see the output is +6dBm.There are a bunch of spurs up to 200MHz, nothing noteworthy above that, I checked to 1GHz. See the attachement. Some of these spurs don't look like theyare harmonics, but it would take time to investigate all spurs. Hope this helps you, bye, Said************************************** See what's free at http:// www.aol.com.<prs10.jpg> _______________________________________________ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts------------------------------------------------------------------------ _______________________________________________ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
