These are inexpensive but seem useful:
https://www.ebay.com/itm/334526399735The picture below shows them applied to a power module. The module conditions:
Input 8 vdc @ 0.36A
Output 12 vdc @ 0.2A
E probe channel 1
H probe channel 2
Seems that using EMC probes might also be useful when designing and/or troubleshooting. Does anybody here do that?
These kind of probes are useful indeed to find sources of certain frequency bands on a PCB. They should be in everyone's toolbox who is dealing with EMC problems.

Yes
I actually made an introductory video on the topic
These seem to be out of stock everywhere (ebay, amazon, aliexpress).
Do you have any other source that can be purchased from?
Loads on ebay china sellers , for as little as £9 with free postage , just ordered a set ..
Hope links are ok ?.
If you want to go cheap, you can even build them yourself, Dave put up a video:

1m RG174/U, wind 10t in 10..25 mm dia coil.
Terminate centers to BNC conn
Shield is connected at one end only to BNC rtn
Finished with insulation dip, tape or similar

Here is a nearly zero cost E probe. It is shown compared to the one in the assortment that I recently bought . It has been insulated since the photo was taken. It outperforms the one at the top by a wide margin ... much less unwanted 60 Hz noise susceptibility.
