offered 20 bucks for this YTO hoping the guy would turn me down.
it produces 18-20 dBm across its rated range. (8-12 Ghz).
it jitters about plus and minus 150 Khz from its tuning point. but that could be partly due to noise from jumpers just thrown across the bench.
need to package and feed it better and then will try to characterize its real stability and noise.
what else ya' gonna' do while hiding in the basement waiting for the looting to commence?
IIRC, YTOs are *extremely* pedantic about PSU noise. This rather asks for an SMU or a really good regulator.
You probably know that in practical instruments they are dithered to get rid of their hysteresis.
this is my first actual experience with the mysterious yig tuned oscillator. (had a vague understanding that they were in some of my instruments, but never had to yank one out to diddle with it).
had also read that they suffer from hysteresis. will go looking for more information about the dithering technique.
thanks!
Another tip: Most have a Mu-Metal shield around them. This means:
- All magnetics far away, please (transformers, fans, ...)
- Dont drop, make dents or treat them rude otherwise, Mumetal is very delicate.
Also dont run then without loading (especially the higher power parts)
Have fun !
