The Fury and other Jackson Labs GPSDOs can be put into manual holdover with the SYNChronization:HOLDover:INITiate command and taken out of holdover with the SYNChronization:HOLDover:RECovery:INITiate command. The phase measurement from the sync:tint? query remains valid while in the manual

[time-nuts] Additional leap second results

Guys, We tested the recent firmware updates for the JLT products, and they correctly output the 23:59:60 time stamp, this firmware even outputs the correct leapsecond timing if GPS signals are totally lost and the GPSDO is in GPS-holdover mode during the actual event. We recorded a video of the

We put together this comparative analysis between the LTE-Lite and LEA-M8F based on our measurements and observations. http://www.jackson-labs.com/assets/uploads/main/Comparative_analysis.pdf We have also noted that the LEA-M8F seems to use the digital power supply for its TCXO. This results in

We have received some additional information from Skytraq regarding the leap second error: The faulty version firmware indicates leap seconds (17) from now to June 16th (two weeks before June 30th). During June 16th ~ June 30th, leap second will recover to 16 and change properly to 17 on June

I work with Said at Jackson Labs. I've been reading the time-nuts discussion for a few years, but rarely chime in. I saw this discussion and wanted to make a couple points. * The LTE Lite time accuracy specification corresponds with the Skytraq GPS receiver's specs page which I have attached.

Said asked me to forward this: Hello Orin, very nice job on the buffer design! This confirms that minor changes in power consumption due to load changes on the board affect oscillator stability. The 10MHz oscillator itself is rated at up to +/-5ppb for load-induced changes, so that is very
