Im looking for a datasheet Wideband PLO (Phase-Locked Oscillator) display model Bonn Hungary Electronics BHE BSVB23 Datasheet. I cannot find anything on their website.
Im trying to solve a gain issue when Im testing it. It seems to work but the specigfied gain at a given frequency isnt matching the manufacturer specifications.
So if you have any datasheet or suggestion / method on how to test/debug the circuitry , I would really appreciate it. Thank you in advance.
Below a few picture for details:
