Try configuring IT to do a survey-in for 24h. And select GPS L1 and L2 only, turn off the other GNSS and SBAS.
The survey is under time mode TM5.
I haven't yet tested mine against UTC or a Maser (soon), but two units against each other show those 10 ns excursions while they're free moving. When their position is frozen, as the survey ends, they achieve 1.5 ns 1-sigma variation between them, with a few ns offset.
