Hi Bill , at first you can look at the kiwi section of the groups. There are many informations and links on the subsection https://groups.io/g/nanovna-users/wiki#Documentation Of course Keysigth , Nat

Keysite, R&S, and Advantest (Tek) all have general tutorials addressing vector network analyzers. Once you become familiar with the basics, you should be able to use any similar instrument. Dave - WØL

I'd be interested in those too!

Copper Mountain and Keysight/Agilent/HP both have lots of tutorial material for VNAs. The other possible source is the syllabus from a class at University of Alberta - during COVID, they sent out a pa

Where can I find detailed analysis, interpretations, insights, and teachings of case studies and examples of scan outputs from various test experiments, so I can learn how to interpret the output and

Thanks for all the great advise. I really appreciate it. I'm still in the process of ordering everthing I need to install my antenna. It involves drilling holes in exterior wall, installing interior a

Not if the transformer has continuity between inner and outer conductors, but it only takes a second, cultivates a good habit and will do no harm. 73, Don N2VGU

Hi Don, I agree – always a good practice to short center conductor and shield together before connecting to an instrument. Even better is to short them together and connect the shorted junction to an

This is good practice before connecting any cable to any instrument. I usually short the inner and outer conductors against the outer conductor of the connector to which it will be attached; I wouldn'

The coax cable capacitance stores up a charge and if you short the ends of the coax together you discharge it. When shorted you can also touch the terminals to ground of you want to be really cautious

Hello, I own the "Upgraded AURSINC NanoVNA-H4 V4.3 Vector Network Analyzer 10KHz-1.5GHz HF VHF UHF 4''" (purchase link is here https://www.amazon.com/gp/product/B083PQ4RXZ/ref=ppx_yo_dt_b_search_asin_

I got a nanoVNA H4 that goes 10kHz to 1.5Ghz. I noticed that it freezes the drawing after a few seconds after startup. The UI is fast and has good respond. The thing is that it just stops refresh the

It's probably not worth putting too much effort into the curve fitting algorithm below a few MHz because I think this is the region where the dielectric losses can begin to cause an increase in ESR wi

Using Excel for curve fitting is a good start, but you need to specify a mathematical curve equation to get the ball rolling. The graphing function of Excel can provide an idea of whether the relation

I don't measure ultra-high Q inductors very often, but my favoured method is to use three ATC 800B porcelain caps in parallel to make up the resonating capacitance. Air spaced caps are generally infer

OK, no problem. Anyone that wants to email me about my last post, please do. Thanks for the info about measuring Q of a cap, I'm building a circuit between forum exchanges, when I get that working I'l
