RSR GNSS Transcoder™ User Manual
4.14.8 SERVo:AGINGcompensation
This parameter is a coefficient that represents the drift of the EFC needed to compensate the natural
drift in frequency of the TCXO or CSAC due to aging. This coefficient is automatically computed
and adjusted over time by the Jackson Labs Technologies, Inc. firmware. This command has the
following format:
SERVo:AGINGcompensation <float> [-10.0, 10.0]
4.14.9 SERVo:PHASECOrrection
This parameter sets the Integral part of the PID loop. Loop instability will result if the parameter is
set too high. Typical values are 10.0 to 30.0. This command has the following format:
SERVo:PHASECOrrection <float> [-100.0, 100.0]
4.14.10 SERVo:1PPSoffset
This command sets the RSR GNSS Transcoder™ 1PPS signal’s offset to UTC in 5.6ns steps.
Using the SERV:1PPS command results in immediate phase change of the 1PPS output signal.
This command has the following format:
SERVo:1PPSoffset <int> ns
4.14.11 SERVo:TRACe
This command sets the period in seconds for the debug trace output on the USB port. Debug trace
data can be used with Ulrich Bangert’s “Plotter” freeware utility to show UTC tracking versus time
etc.
This command has the following format:
SERVo:TRACe <int > [0,255]
An example output is described here:
08-07-31 373815 60685 -32.08 -2.22E-11 14 10 6 0x54
[date][1PPS Count][Fine DAC][UTC offset ns][Frequency Error Estimate][Sats Visible][Sats
Tracked][Lock State][Health Status]
Please see the
SYNChronization:health?
command for detailed information on how to decode the
health status indicator values. The Lock State variable indicates one of the following states:
Value
State
0
TCXO/CSAC warmup
1
Holdover
2
Locking (TCXO/CSAC training)
