[time-nuts] z3816A Problem

2009-03-25 Thread Mitchell Janoff
I'm having a problem with my Z3816A. The health monitor and self tests show the unit is fine, but it never moves out of the Power-up GPS acquisition mode. I've tried several antennas (one of them currently working fine on a z3801 unit). The z3816A shows it is tracking anywhere from 0 to 6 satellite

Hi Magnus: The reason F0 = 1.023 MHz is that it's also used as the basis for the data bit rates. The L1C/A code is 1 ms long @ F0 rate. The L2CM (Moderate) code will be 20 ms long @ F0/2 The L2CL (Long) code will be 1.5 sec long @ F0/2, so maybe F0 should be 511.5 kpbs? I discovered that the Tri

Hi: There are three new civilian GPS signals, L1C, L2C and L5. http://www.prc68.com/I/DAGR.shtml#GPSs The original civilian signal, L1 is at 1575.42 MHz (154 * 10 * F0, F0=1.023 MHz). L1C is at the same frequency as L1 but uses the code like Japan. The new L2C signal is at 1227.60 MHz (120*10*F0

Sorry to jump in, but does anyone have any thoughts on whether this might also be involved in the odd year rollover issue seen on many TrueTime devices? This is the issue where the work around for the TrueTime clocks is to use the F68 command to set the year explicitly to 1996. From what I un
