Questions, corrections, measurements. This is a reference project rather than a supplier, so there is nothing here to quote and nothing to sell you.
01 / Send a message
Tell us what you are trying to work out.
Specifics help enormously: which interfaces, what frequency, the constraint boxing you in. A photograph of the joint or the enclosure beats a paragraph of description nine times out of ten.
Correcting something on this site? Quote the page and the figure. Corrections push this reference forward faster than anything else we do, and we credit them unless you would rather stay anonymous.
By email
No mailing list is inferred from a message. Nothing sent here is passed to a manufacturer.
02 / What reaches us
Four kinds of message, four responses.
A question
Compatibility, part selection, a figure you cannot square with another one. Answered straight back, and written up as a page if it keeps coming round.
A correction
Something here is wrong, or the vendor revised a drawing and we missed it. Quote the page and the figure. Corrected pages carry a revision date.
Measured data
Your own sweeps, above all on pairings we have never covered. Send the method and the sample size along with the numbers and we publish and credit it.
A gap
An interface or transition missing from this reference. These drive most of what gets added.
03 / What to expect
Roughly how long things take.
| Message type | Typical response | What happens next |
|---|---|---|
| General question | 1–2 business days | Answered by email |
| Correction to a page | 1–2 business days | Verified, then the page is revised and dated |
| Request for raw sweep data | 2–4 business days | Touchstone files sent where they exist |
| Submitted measurement | 1–2 weeks | Reviewed, published with credit if it holds up |
| Request to test a new pairing | Varies | Queued; recurring requests get prioritised |
Everything here gets written by us around other work, so treat the timings as honest guesses rather than promises.
04 / Before you write
Three quick answers.
-
shopping_cart_checkoutCan I buy connectors or cable from you?
No. Green Button sells nothing: no parts, no assemblies, no consultancy. We also decline to name preferred suppliers, because the moment we do, the comparison pages stop being worth your time.
-
descriptionCan I reuse a table or figure from this site?
Yes, with attribution and a link back to the page it came from. Tell us what you need, partly so we can wave at you if the information gets revised later.
-
handshakeDo you accept sponsorship or review manufacturer content?
No on both counts. No manufacturer funds, sponsors or reads anything here before it goes up, and there are no affiliate links anywhere. Product announcements reach us, get read, and go no further.
