HP/Keysight 66311B magnetic field leakage
electronomicon:
Thanks for the suggestions!
Ideally, I’d like something that I can fit into my cupboard together with the devices, because this is all in my living space and I don’t really have room for a large separate solution. This restricts the size to maximum about the same as the devices.
But if that doesn’t exist and/or is too complicated to set up myself, I’m also fine with the current state of the noise problem.

Thanks, this was really helpful!
To apply this to my use case:
- I have two devices, fused to 250 mA and 500 mA on the line input.
- I measured my line voltage to about 235 Vrms.
So I should look for a transformer rated for 230 V on the primary, 15 V on the secondary and at least 11,25 VA. Or is there any reason I should not hook up both devices to the same transformer?
Edit:
This then seems to be a viable option?
I also looked specifically for halogen transformers like the one used in the video. But I find a lot of them are labelled as “electronic transformers”. What does that mean? Will these work or are these electronic replacement circuits for a traditional transformer and will behave differently for this specific use case?

If the transformer is rated for atleast 11.25VA i dont see a problem hooking up two devices.
It must be a real transformer, Switching (electronic) power supplys would not work.
The NT 12VA 2X15 should work perfectly, you can use both secondary in parallel if you want.
Hydron:
It's worth noting that the bucking transformer is only useful if the field leakage is made worse by a transformer starting to saturate. Don't assume that it's a guaranteed fix unless you've tested with reduced voltage first (hence my Variac suggestion - it's not a permanent solution but a very good way to test before mucking about with other transformers).
