correctionNanos in tsm.json file

[mruizglz]

I am measuring the PPS deviation from a Grand Master clock PPS in my PXI6683h using NISYNC in Linux. I am getting an offset in the measurement. What is the purpose of correctionNanos parameter in NISYNC? Is there any document detailing the behaviour of this parameter?

The value adjusts the hardware counter in the PXI6683h.

I get a PPS offset of around 122ns compared with my Grandmaster GPS PPS signal.

I am using NI-SYNC 2024Q1 in Linux.

Does anybody have the same problem?

Any answer is appreciated!

I have modified the correctionNanos to 160 in the tsm.json and the offset is fixed
