Great video. It's fascinating how much microwave RF is dependent on interesting physical components and final operation still dependent on experimentation. One recommendation is to use peak hold on the HP 8566 when conveying frequency response envelope. Thanks.
Learn your random numbers, I have over 20 years of European Space Agency testing and inspection experience. I had to make up random numbers for test results to approve components for launch. My claim to fame, I've now 20 years of falsified & forged parts in orbit! :D
It should be possible to modify the working frequency range of an isolator by attaching magnets to it. It would be interesting to find out which tuning range is possible with this method.
You can similuate testing by that method too, say you need to supply plots to your customer showing that the isolator works at max & min temperature ranges, if you but a neodiddlydum magnet near the component to adjust its ambient plot then you can successfully falsify the data. :) Contact engagement seperation of the internal contact forces can also be falsified by simply putting acceptable values in any test data for your customer. Thankfully on this particular device coupling proof torque testing (which in some companies isn't acrried out) doesn't apply as the connectors are secured to the housing by screws. In space applications the screws would have to be secured to the housing using an adhesive usually araldite, hardness sample that Qa will test can be premade and kept aside so that they will always pass this Shore D test. More, much more I could say :)
Thanks Kerry for sacrificing the isolator to let us see the internal construction.

Great. Plz use dark background to keep the camera focused.
Is the polarity of the magnet important to which "way" the RF field flows? If you reversed the magnetic from on orientation to the other?
can this be used instead of a relay between my transmitter ~ receiver to my feedhorn @ 10368:100

The outside case is needed to complete the magnetic circuit
Super interesting thing.
A dead short on DC but isolation at RF-frequencies - Black magic!
