Can I use the TG Sync connection from the TG44A with the 1PPS/TG Sync connection on the BB60C?
What are the advantages of using the sync?
Additionally; Is the 10 MHz Ref Out on the TG44A any better than the internal frequency reference on the BB60C? I have the extended range variant of the BB60C. Is the only advantage to have them on the same frequency reference?
thanks,

Yes, the BB60C can be connected to the TG44A using the TG Sync signal to enable scalar network analysis, which provides about 600 frequency/amplitude signals per second.
When doing scalar network analysis, there is no advantage to having the 10 MHz time base connected (the TG reference is uncorrected 1 ppm, the BB60C is corrected, typically < 0.1 ppm initially). But if you need frequency lock between the BB60C and the TG44A, you can connect the TG44A 10 MHz out to the BB60C 10 MHz in. It may be 1 ppm off, but the frequency will be exactly locked (typically when testing phase shift using streaming I/Q data when 0 ppm *relative* frequency error is required).
