How does a YIG Tuned Oscillator Work? Powering Up an HP YIG Oscillator

- In this video, I explained the operation principle of a YIG tuned oscillator and demonstrated the tuning of an HP 5086-7023 YIG oscillator (2.7 GHz to 4.2 GHz). www.kerrywong.com/2020/10/16/p...
Check out www.kerrywong.com/2014/08/03/w... for a teardown of the YIG oscillator used in the Wavetek 907 microwave signal generator.
From what I’ve read, YIG Spheres can be tuned up to 50GHz.
Excellent, never seen any of those inside. I’m watching the video with great interest.
Thank you for sharing your videos. It's fascinating to learn a bit about these things as someone from a non EE background.
Hey Kerry, good to have you back on the air again! Nice explanation and demo. Stay safe!
Thanks Dino! Yeah, I have been quite busy lately... Stay safe as well!
Very interesting, thanks Kerry, I wondered how the YIG oscillator worked.
Good to see a new video from you!
Thanks! Have been quite busy lately...
Great Video and great way to explain things. You made it so easy to understand. Thank you for sharing.
Great video and well explained! 👍
Excellent video as usual Mr. Wong.....thank you.
Excellent explanation. Very clear and instructive. I logged here now. Thanks.
Excellent tutorial. Thanks.
Thanks for the video. It was interesting for me.
EXCELLENT DEMO of a YIG osc. !!!

Thanks a lot, now I know more about these magic devices!
good one. i always wonder what's inside a yig oscillator
Thank you for this video.
Excellent video. Very helpful to me.
What is the voltage/current range on the FM coil?
The -10 bias. Is it -10 relative to +20v ground?
The FM coil current range is similar to that of the main coil, up to 200mA or so.
@@KerryWongBlog thank you Kerry wong.
You give me insights.
I find it very kind that you bother to answer casual questions on the comments.
Accelerated/discellerated charged particles in a material, emit specific electromagnetic waves.
I wonder if it works the other way around, reverse causality.
Those specific electromagnetic waves would be absorbed in the material, as negative lumincess, causing accelerated charged particles.
Do quartz generate second harmonics in the microwave range, as well?
Do yattirium iron garnet is an anisotropic resonator, or isotropic resonator?
Is being anisotropic resonator, makes this material special?
Thank you Kerry for sharing this video, when I am measuring the YIG oscillators, I found out that if I connect a DMM into the FM tuning circuit in series will contribute to serious phase noise, do you think there is any method to isolate the DMM while measuring phase noise?
Perhaps you could try using a current probe?
@@KerryWongBlog Thanks Kerry for the reply, definitely will try it
You learn by asking questions.
What is the impedance of this transmitter? For impedance matching.
hi, thanks... , plz how running projector acer dlp Without lamp halogene ,, or desactive test lamp ....hack board communication 3 optocouplers...thanks
I'm wondering if the frequency changed much with orientation?
The frequency doesn't change in any measurable way as the environmental magnetic field is very weak. However, YIGs are supposed to be mounted only in the way that is specified by the manufacturer (in this case it is vertical) as there are delicate components inside that may be damaged if mounted incorrectly due to external forces such as vibrations, etc.
What could be the problem with both fans in my Bk Precision 1790 power supply not working… need help
I have several vintage HP & Other Oscillators along with several parts. I'm looking for someone that has knowledge on how to use & may be interested in purchasing located in Alhambra
Please.
Can someone explain how the -10dc biasing was done?
He connected the( +)10dc terminal to the (- )of the 20v output on the power supply?
Or
He used an offset function on the power supply?
I don't understand.
Its -10bias relative to what?
In other words, where is the other terminal of the -10bias, to create a loop with?
I do understand that -10 is the mean average of a square wave with an offset of -20.
Hi David, the +/- bias are with respect to ground (pin 8)
@@KerryWongBlog thank you all so much, kerry wong. Mighty kind of you to answer questions on the comments.
Keep doing those marvellous videos.
Hello, if anyone can help, I need the firmware for the HP 8594A, thank you.
This is how the pyramids used to work. Center taps.
Our magnetic field is gone now compared to 50k years ago.
I used to be head of QC for Wave tech California.
