The thread spawned an interest in me to purchase one of these on a small eBay sale for $120
It's got its quirks, but suits me for anything I can possible think of on the lower frequency end.
With my new scope to be written about, I measured the sync phase offsets on a sine wave with the beautiful GolTek software (the original supplied software wouldn't let me write a DLL file to system32, even with admin privileges or manual copying of it beforehand
)
100kHz: Sync Phase: -1 degrees / -20ns
1MHz: Sync phase: -9 degrees, -25ns, sync jitter: +/- 5ns or 3 degrees
10MHz: Sync phase: -70 degrees, -20ns, sync jitter: +/- 4ns or 10 degrees, (sine at this point)
20MHz: Sync phase: -160 degrees, -25ns, sync jitter: +/- 1 ns or 5 degrees
20MHz+: (Mostly noise at this point.)
That seems pretty useless for anything over 1MHz for sync.
Ah well, all for now.
EDIT: Odd, his phase correction turned off reduced the error by ~10x, 1 and 10MHz offset becomes ~2ns now. What's up with that? That's significant for 10MHz, since phase is now only +/- 5 degrees instead of 70.
A goodie shot, transfered through a 3.5'' medium of some kind, I remember those
