Good day for everyone, please if somebody have this schematics and recovery floppy image send me

Or wright here if you know where can i get this information by paying...
Advantest service and support group as usual give an answer - very old equipment, unsupported, buy new one, blablabla etc...
By the way - very hard to find some practical information of any VNA equipment from this company,
Advantest close everything and everywhere (compared to HP/Agilent/Keysight)
