Hi, my name is Marco from Italy.
I've been using Advantest R3751A VNA since two days ago when a sad message popped up from the screen: "Synthe Unlock".
Not immediately though: as soon as I power on the unit, it works fine for a few seconds, then the quoted message pops up.
The Service Manual of this instrument is nowhere to be found.
Any idea?
Cheers
