Where can I find reliable cable properties for lock-in amplifiers?

AI Thread Summary
The discussion centers on finding reliable sources for the properties and characteristics of cables, particularly for lock-in amplifiers. The original poster is specifically interested in the speed of propagation for coaxial cables and considers using the Handbook of Chemistry and Physics but doubts its usefulness. Participants suggest looking at manufacturer datasheets, noting that companies like Belden provide stable and reliable information. There is a discussion about the acceptability of citing manufacturer datasheets in journals, with the consensus being that it is acceptable as long as the datasheet is stable. The original poster finds a relevant datasheet and plans to reference it, acknowledging the importance of including product numbers or release dates for accuracy.

Hey all,

I'm doing an investigate into lock-in amplifiers and am looking for a book, or journal, which has a collection of properties/ characteristics for cables?

For example, I'm particularily looking for a reliable source to quote the speed of propagation of a particular co-axial cable!

I've had a thought about using the latest edition of the Handbook of chemistry and physics; but am not hopeful it will contain what i need!

Hopefully someone has encountered a relevant source

Thanks!

Welcome to the PF.

It would probably be easiest to look at the datasheets for the cables you are interested in. You can find the datasheets at the manufacturer's websites. Belden is a big manufacturer of cables, for example.

Thanks for the welcome!


Cheers, I will have a look thank you.

I thought i'd just check, Is it acceptable to quote a manufacters reference sheet in a journal?

Hmm, that's a good question. I would think so, as long as the datasheet is stable. Datasheets for Cat-5 and Cat-6 twisted pair cables are quite stable. Standard types of coax cable like RG-8 should also have very stable datasheets.

I've found a datasheet with what I'm looking for, thanks...

As for the referencing i'lll investigate further whether or not I can reference it; like you said if it's reliable i don't see why not!

If worse comes to worse, ill reference it and hope for the best!

Thanks again for the quick reply
 
In case of doubt, quote the data sheet with whatever product number or release date the manufacturer put on it.

When the properties change, the manufacturer should either change the product number or re-release the data sheet with a different publication date.
 
The book is fascinating. If your education includes a typical math degree curriculum, with Lebesgue integration, functional analysis, etc, it teaches QFT with only a passing acquaintance of ordinary QM you would get at HS. However, I would read Lenny Susskind's book on QM first. Purchased a copy straight away, but it will not arrive until the end of December; however, Scribd has a PDF I am now studying. The first part introduces distribution theory (and other related concepts), which...
I've gone through the Standard turbulence textbooks such as Pope's Turbulent Flows and Wilcox' Turbulent modelling for CFD which mostly Covers RANS and the closure models. I want to jump more into DNS but most of the work i've been able to come across is too "practical" and not much explanation of the theory behind it. I wonder if there is a book that takes a theoretical approach to Turbulence starting from the full Navier Stokes Equations and developing from there, instead of jumping from...
