tinySA observing E and H fields

[@pravrao]

Thanks for your video, this is exactly why I bought a tinysa.

Excellent Erik. Been enjoying all your videos.

Thanks Erik! I really enjoy and appreciate your videos! one question, does the H-probe have any particular/recommended sizes or diemensions, I mean length, loop radius, etc? Tnx very much!

[@ErikKaashoek]

The larger the size, the more sensitive, the smaller the size the better you are able to locate a source on a PCB. So it is always a compromise. Why not make a small AND a large one? Google can find a lot of material on building your own magnetic probes. In general, size is not critical

That’s a great idea

Hi Erik. I downloaded the TinySA software but my computer tried to prevent me from opening the executable. I ran it anyway, but some people may be hesitant to download and use it for fear of viruses.

Microsoft decided that anything you download from the internet without a security certificate can not be trusted. For now I don't know how to create an installer with the right certificates without having to pay

Thanks

Great video! Question, I noticed that you didn't split the shield on your H Field probe, all the ones that I've seen have the have the shield split, what am I missing? TNX 4 the upload! 73 N8AUM

[@ErikKaashoek]

As long as the shield is not connected all around it will work. The simplest way to do so is not connecting the shield at the end. A better way (more balanced to eliminate picking up E field) is to connect the shield at the end and make a shield split in the middle of the loop so each shield seeing from the outgoing coax is equally long. The simple way is a bit worse at shielding E field but will equally work for probing H-field.

can i see rds and stereo level in the tinysa ,if yes let me have a video of it i want to buye one,to my hobbie ,when i play with fm tx ,but useless if it not show bandwith less than 100 khz or even the fm deviation of the 75 khz or the 57 and 19 thanks

[@ErikKaashoek]

Feel free to read the specification at tinysa.org/wiki/pmwiki.php?n=Main.Specification and decide if the tinySA is useful.

Are you using a clone?

[@ErikKaashoek]

No

@@ErikKaashoek I saw your other video where the genuine had a laser etch logo and the fake had the bright painted look. Thanks for your great videos.
