You can measure the length using just one port. Leave the far end of the cable open circuit. For a cable that long, you need to set the frequency range to something like Start:50kHz, Stop 150MHz.

In order to measure the electrical length of some coaxial cable you need to know its propagation constant.? Then you use the Smith chart to find the one-eighth wavelength (one quarter of the way

Best way to accurately measure the length of a piece of coax is with a tape measure. If you insist on using your nanovna, read the thread around this post:

Well, I finally downloaded the OneOfEleven firmware and the PC app. Installed and tried them this evening, using the App to load the firmware. _WOW_!! I've tried the other PC softrware, and I like

Just got my unit so I am playing with after it actually found an issue with the HF long wire Antenna i strung up yesterday I had 2 tiny strands of the shield caught up in the lead wire so for me this

David, you are correct, NanoVNA-QT is the application designed for the NanoVNA SAA-V2.2 (SAA-2.2, 2N etc). NanoVNA-Saver is supposed to work, but as noted by a couple of SAA-2N users, has some

I have not yet tried mine using SAVER. However, due to different architecture and oscillator, I was/am under the impression you need an application different than that embodied in SAVER. According

Yes, Jim, I've seen that log plot at HP. I need to generate one for my radio room door! Dave - W?LEV

I'm looking for a copy of the old HP direct reading cps to Hz conversion graph - the one plotted on semi log axis, so it's a curve. We've got plenty of (old) test equipment in the labs at JPL that

Thanks, Christian. Any information you or others can provide would be greatly appreciated. - Jeff, k6jca

Hm, I distinctly remember a Rita Meter... She was a lovely maid. Raymond

The symbol for meter is m (lower case), not M — there never was a Mr. (or Ms.) Meter. 3.6 km/h = 1 m/s. Rohde and Schwarz has written the best summary of all this (on their career site, because

Thanks, Raymond. Meters = m (lower case). Dave wrote: -- *Dave - W?LEV* *Just Let Darwin Work*

Yes, engineering notation employs a subset of standard SI prefixes with factors of 1000 between them. Also, their spelling, including capitals, conforms to SI. Is it? The SI unit symbol is m

Below 30 MHz, so long as you keep it short and sweep, you can get away with (short) clip leads. When lengths approach 1/20 of a wavelength in free space, you should consider and use more rigorous

Mega and Giga are STANDARD abbreviations for powers of 10. Mega = 1E+6 Giga = 1E+9. Pico - 1E-12. Micro = 1E-6. These are all STANDARD engineering notations! Oh, yes, and picoFarad =

In the example, k is correct but K wouldn't lead to confusion because the capital rule applies to *units* (Hz in this example) and k is a *prefix* (scaling factor if you will). Raymond

Your question has insufficient information.? Explain what you are doing and what your observations are.? Not getting any results makes no sense.? What readings don't change?? What are the

That is true. Engineering notation conforms to the SI unit system. Engineering notation applies to *prefixes*, not *units*. Hertz is a *unit* in the SI, milli, mega etc. are *prefixes* (to
