The AC network analyzer section might be split off to something like Power quality meter or Power quality analyzer. The analyzer would be like those from Dranetz, Basic Measuring Instruments, or Reliable Power Meters. Glrx ( talk) 22:00, 7 April 2011 (UTC)
Calibration of VNAs is a very complex topic. I wonder if there should be a page devoted to just the calibration of VNAs. Personally I don't have the expertese to write such a page in any detail. — Preceding unsigned comment added by 213.78.42.15 ( talk) 11:11, 18 August 2012 (UTC)
I've had an attempt to expand the calibration section. I don't know a lot about this topic, and are in the process of learning myself, but I know far more than what is currently in the article. Drkirkby ( talk) 10:59, 20 September 2012 (UTC)
"See scattering parameters#Measurement of S-parameters."
The above link just after the first paragraph in the Architecture section seems out of context -- does it belong somewhere else? -- Dougher ( talk) 17:29, 3 October 2012 (UTC)
Article needs info and references from more than one manufacturer or it will get tagged as biased and/or an advertisement. Right now it's very Agilent focused. -- Dougher ( talk) 17:58, 3 October 2012 (UTC)
If we look at just the Agilent application notes, we see some are listed as notes, some as references, and some as external links. The Agilent application note "Network Analyzer Basics" http://cp.literature.agilent.com/litweb/pdf/5965-7917E.pdf , is listed in both Notes and External links.
I've added as a reference as book on VNAs, but I've not made a reference to it anywhere in the text simply because I don't know how to do it properly, whilst keeping to the same format as other items in the "References" section. I suspect the references section should be in a difference format, so its possible to put a reference by a name, since it is clear that the same application note can be referenced in many places.
It seems to me the application notes should be references. The lot needs sorting out I feel, but I'm not sure how best to do it. Drkirkby ( talk) 10:53, 11 January 2013 (UTC)

I put a section for nanovna in the article and it was reverted by someone who obviously knows NOTHING. The nanovna is a huge advance in making test equipment available to e.g. amateur radio operators at an affordable price. The comment by the person who reverted it shows that he or she has no idea, and there were references about it he or she plainly did not read. Nanovna is not a brand, but a category. It's not "cheap" it's a way of getting sufficient accuracy with a $100 credit card size device rather than requiring a huge instrument costing tens of thousands of dollars. Conscientia ( talk) 01:00, 18 January 2022 (UTC)
I suggest that the reversion note was insulting and not factual. As is the comment before this one that nanovna is a brand name. Search for it on Ebay and you will find several manufacturers and sellers. It is the name of a class of device. Maybe a device you can keep in your pocket that is able to immediately give the swr of a ham radio antenna and much more is not remarkable to you, but your prejudices are not the criterion for including in wikipedia. Get your facts strait, stop insulting the thousands of people who use this relatively new device, and reinstate the inclusion. Conscientia ( talk) 14:05, 24 January 2022 (UTC)
...you should have noticed that it's closer to the size of a credit card than it is to the lab instruments. Why did you have to be so snarky and counter-factual in your note on the reversion and why do you keep doing that? You have successfully chased me away from posting on Wikipedia. Thanks.

I think that the article at least should mention that inexpensive VNAs are available on the hobbyist market. For the first time, this particular kind of test equipment has become available for non engineers to use, it has gone from an strange box sitting somewhere in a lab to something that the average person can own and should therefore be interested in. It is having a great effect on the state of the art of non-professional RF experimentation, in a similar way to inexpensive software defined radios. The first of these inexpensive analyzers was called the NanoVNA by its creator, and NanoVNA may come to be accepted as a generic term for these devices. For context they go up to 1.5 GHz and cost around $50. I recently bought one that looks almost identical called a LiteVNA for about $120 that can take measurements up to 6GHz. We needn't mention any specific name brand, but we should should include something. People will be searching for information on VNAs after seeing them for sale, and they will end up here.

"Network analyzers are used mostly at high frequencies; operating frequencies can range from 1 Hz to 1.5 THz. Special types of network analyzers can also cover lower frequency ranges down to 1 Hz."
The first frequency should probably be higher, but what should the typical lower limit be be, 1 MHz, 1 kHz?? 150.227.15.253 ( talk) 12:03, 15 March 2023 (UTC)
