DC coupled 2.7 GHz Active Probe Project - Now Available!

Dennis Frie:
Thanks for a great product. A 2.7 Ghz active probe at that price-point is amazing. :-+
This is now my go-to probe to verify signal integrity of digital interfaces. Compared to the Siglent SAP2500 we have at work, this is an amazing price-performance ratio.

i have MG CHEMICALS 841WB-150ML NICKEL CONDUCTIVE COATING bought from digi, its worth it sure better than nothing, but you need airbrush spray tool and compressor, tubing etc... using brush is a no no as conductive particles will just stick to the brush, not the enclosure to be coated. and EM protection is in term of dB, more layers, more dB attenuation, maybe 2 or 3 layer is ideal, more than that you wont get further noticable protection. if you tight arse, 1 layer can give you some protection already. ymmv.

yes, painter's skills are really needed to be applied here, covering/masking from spray here and there etc... and conductive particles is special type, we need to keep stirring spray tank on each spray pass otherwise they will settle to the bottom very quickly and clog the spray tool.

most likely yes, my agilent 1141a has silver coat on inside of enclosure, its durable and scratch resistant type, unlike my water based coating type. ymmv.

Hi Dennis, thanks! I'm glad you're enjoying using the probes and are making good use of them :) It really brings me joy that they are providing a useful service!

@Mechatrommer, I've tried a couple of attempts at painting with a conductive paint, by hand. It's not worked very reliably, so I'm not planning on using that method going forwards. It's just not worth the time to be honest given the low price of the probe. I'll leave it to the customer to use copper tape if they are so inclined. I'm working on a new version of the datasheet with instructions on applying copper tape properly.

I only have one probe remaining in stock. I am in the process of ordering/manufacturing more. I've unfortunately been hit by part shortages up till just a week ago, but they seem to be resolved now. My PCBA manufacturer is about to start kicking into gear in the next few days.

@lasmux,

It might be easier to go the other way- use a conductive material for the case (or part of it) and then insulate it.

Thanks,
Josh

Yeah, this is something I've been considering. I originally discounted the option, but I think it could be done. Perhaps a conductive body, but with just the tip around the inputs as a non-conductive part.

Probes are now out of stock. I've put up an interest form on the product page so you can get notified when they go back in stock.
