[time-nuts] Network Syncronization

Hi, This querry of mine may not be related directly to clocks, but I was just wondering if someone here might know about this! As CDMA networks (and now GSM as well) are SYNCed by GPS, I wanted to know, how a degradation of this sync would affect the network's performance parameters like call

10 or 7uS. I wonder if the accuracy limits have been modified for meeting such data rates?!. What do u say abt this? Regards Faisal At 20:26:49 -0500, Sat, 03 Feb 2007 Mike Swrote... At 07:11 PM 2/3/2007, Phaysal Khan wrote... Can anyone tell me, how important is timing for network

[time-nuts] CDMA Networks: Timing Requirements

Hi, This would be my mail on the list after a looong break. Hope everyone is fine. Can anyone tell me, how important is timing for network synchronization ( i am looking forward to some quantitative values), how much accuracy is expected from timing references, especially GPS and what are the

[time-nuts] Sawtooth Effects in 1PPS

Hi group, Hi, I am currently working on problems with GPS timings, as I said in my previous emails. I presented some of my problems and got quite helping feedbacks. I just wanted to update regarding my progress If u visit the page http://www.leapsecond.com/pages/m12/sawtooth.htm you

Re: [time-nuts] Discussion of precise time and frequency measurement

John, At the momet I m trying to do some similar stuff. I want to compare PPS output from two different rcvrs, the reference being Leica MC500 and the subject recvr being M12. but I am having problem with my oscilloscope which is a Tektronix one with 300 MHZ range. It is not locking on to the

Re: [time-nuts] time-nuts Digest, Vol 24, Issue 50

Hi Group, I have been using Leica MC500 PPS pulse and want to get the pps output from that. could any one provide me the socket drawing for the PPS port of Leica MC500 rcvrs. Regards Faisal - How low will we go? Check out Yahoo!

[time-nuts] Interference effects to GPS timing

Hi, Thankyou for your responce. My main prob is not to avoid interference but to see how does a GPS timing rcvr behaves in the interferece environment. I have tried to search for articles/papers on interference effects on GPS timing rcvrs, but was unable to find any good stuff. Although GPS

Re: [time-nuts] time-nuts Digest, Vol 24, Issue 47

Hi, Thats a good stuff grp. I will going thru these and get back to u soon. by the way... i will be doing some experiments with some GPS rcvrs today as well. Regards Faisal - Talk is cheap. Use Yahoo! Messenger to make PC-to-Phone

[time-nuts] GPS Timing in Interference Environment

Hi, I am new in this group, and wanted to discuss something abt GPS timing. I am working on GPS system signals from timing point of view. I want to see Effects of Interference(CW) on GPS timing receivers. At this stage I am mainly interested on what will happen to the timing receiver itself
