IQCM-110


Overview
ISSUE 1; February 2016 Description A GPS disciplined OCXO incorporating GPS receiver unit, to give 1PPS and 10MHz output.
Holdover stability up to 1.
5µs over 24hours, achieved using an adaptive algorithm.
Standard NMEA0183 data is available to the user via serial port.
Frequency stability better than 1E-12 Working States (Reference Drawing): Run1: Fast track.
Adjust the OCXO 10MHz output frequency quickly to track the GPS.
Run2: Slow track.
Adjust the OCXO 10MHz output frequency slowly when phase error is in the defined range.
Holdover: No GPS input present; an algorithm enables adaptive modelling of the frequency stability of an OCXO with reference to the GPS timing signal.
Free Run: Clock module powered up with no GPS input.
Note1: The IQCM-110 should be left powered and running for 7 days minimum before operation to allow for the OCXO's internal drift to stabilise.
Note2: The adaptive module algorithm can be built after two days operation with good GPS signal, however this data wi...
