It is not so much being interested in a particular freq, it has to do with improving my knowledge of analog circuitry. I am wiz with digital and knowledgeable of basic analog, but I would like to know

Will check out Rhode and Schwartz, as I bought one of their scopes last year. Thanks Sent: Wednesday, October 13, 2021 9:43 AM To: '[email protected]' <[email protected]> Subject: Re: [tinysa] Filters

James, all of the recommended texts the group members suggested are good sources of basic spectrum analysis info. I could also recommend the following from Rhode & Schwarz as a great reference as

If you are only interested in Audio Frequency circuits, there are a couple software programs that use a sound card for audio tests. I recently did a post on my blog that covers one of them and

Thanks Frank!

Hi Jim, Look for books by Bob Witte or Joe Carr. Both can be found used cheaply. There are others but these two are very well organized and written. 73, Frank K4FMH --- Frank M. Howell, PhD Ridgeland,

For the original nanoVNA (nanovna-users group) look on the group Wiki for the current “approved” vendors. The list changes from time to time and there are a bunch of clones out there which, for

I bought my TinySA on Amazon, and it checked out as real according to the test tinySA asks you to do. I will check out R&L. Sent: Wednesday, October 13, 2021 6:50 AM To: [email protected] Subject: Re:

The last time I looked, virtually all of the NanoVNAs being sold on Amazon were knockoffs. If you’re in the US, suggest R&L Electronics. From: "[email protected]" <[email protected]> on behalf of

Dave, Just went to Amazon, and there seems to be a range of nanonVNAs for sale. I would probably opt towards a higher end unit, do you have a suggestion? Sent: Wednesday, October 13, 2021 6:36 AM To:

Dave, Do you have a link to that group? Michael, Sounds like a good suggestion, except that I do not own or use any Apple products. Sent: Wednesday, October 13, 2021 6:36 AM To: [email protected]

I recommend the AudioTools suite of tools from Apple iOS for doing all kinds of audio measurements. The senior developer of the product was the chief engineer of the audio line of test products from

One of the nanoVNAs is what you want to do that. There are a couple of groups.io groups for those. I’m a co-owner of the nanovna-users group and if you join that group there is a ton of information

Thanks Dave, Can you recommend a book for the types of measurement I want to do. Evan suggested that I am using the wrong instrument. Jim Sent: Wednesday, October 13, 2021 6:07 AM To: [email protected]

Morris Engelson’s book on spec ans from the Tektronix Measurenents series is good, and downloadable from the TekWiki site. Also, Dan Welch’s book from the Tektronix Concepts series is good and

Thanks Evan and Clyde, I would like to read up on SAs but can find no decent book on them on Amazon. If you have a reference I would be interested. That being said, I do not really plan to do much in

Hi James, There are two different "nano" based devices that are cheap and available for RF and RF circuits measurement.? Each has its own strengths and weaknesses.? To simplify (ALWAYS dangerous, so
