Having a M12+Timing GPS driving the 1 Hz input of my PRS10. I decided to upgrade my house referenc switching to a Tbolt as the 1 Hz source. First I did some time analysis using my HP 5372A controlled by my FTS 4060 Cesium standard that I did turn on beam current three days ago to allow it to settle. Tests showed maximum deviation of 2 nsec with the Tbolt over 1000 seconds and 63 nsec with the GPS (20 nsec with Sawtooth Correction) Again 1000 seconds. Plot's are available but exceed attachment size. The output of the PRS10 in turn disciplines an Oscilloquartz 8600.
Here are my questions: Are 2 nsec acceptable for a Tbolt What should the Tbolt loop time be for this application What should the loop time be for the PRS10 What is the long term performance of the Tbolt and what is the contribution due to the GPS signal. What is the resolution of the Tbolt detecting and correcting the 1 pps and is it done by changing the OCXO frequency for short periods. My tests show a slight change. Does any one have a similar setup using a Tbolt and 1 pps input to a PRS10 and experience to share. Thanks for any help.
