Hi,
today I have dismantled the YO loop assembly, which contains the YTO as well as severak directional couplers etc., see here, this is my unit:
The YTO is the following one
and the PCB can be seen more clearly in this pic:
Does somebody have experience with these HP YTOs? I will test it today, but probably someone has some experience and can give a few hints.
I see a testpoint with +5, I assume this is +5V supply. There are two further testpoints for +20V and -40V. I wonder whether I need all these voltages, or just a few?
Best
Tobias

Yes, it is possible to test the YTO out of the box. It usually needs +15V, -5V. Heater is not necessary for it to oscillator.
Be very careful about the FM coil. I would just tune the main coil only. You need an SA to watch the output. It's usually at +10dBm.
