This is a phase plot of my number two 5680a vs Thunderbolt.
The X axis is in seconds, Y is phase difference measured by
a Racal-Dana 1992 counter with GPIB interface. The big spikes
are markers representing human interaction, typically changing
the frequency offset command.
I calculate the daily drift to be about 5e-11 which compares to
the spec of 2e-11 per day.
The other 5680a, the one that pulls 340 ma from the 5 volts,
is far better than this.
