I conducted a small test with IP5303. IP5303 does not work longer than 30 seconds with a load that consumes less than 65 milliamps. Nanovna consumes 90-110mA. With such a current consumption, IP5303

Hi, That's for you : @edy555 edy555 released this 2 hours ago in-device TDR support (contributed by @cho45) add scan command for multisegment scan excess 101 points fixed invalid sweep at the narrow

Hi Rune, I tested a BP-filter and I am wondering why the VSWR plot is interrupted. If you take a look at the attached screenshot, there is no VSWR line from about 268MHz till 846MHz. A tested

Not yet but forum member hugen is looking into something to help with this. Stay tuned...may take a week or two.

Bo I am the owner of RFzero (THANK YOU!) and of three, soon to be four, Nanovnas. While it does not fundamentally alter the discussion here, The Nanovna only has two frequency ranges: 55kHz to 300 MHz

Is there build firmware with battery indicator, 1500 MHz and big font ? I only found with small font.

Hi Herman, That is really strange. However, your Nano is not lost -just buy a cheap power bank that puts out 5v and use that to power the Nano, which really runs from 5v, not 3.7v. In fact, you can

Its time to give Rune a cup of coffee! Where is the paypal button?? :-) Peter Op 28-9-2019 om 15:06 schreef Rune Broberg:

Hello yin&pez, Thank you for introducing the topic of errors of error-models. This discussion is very interesting. To help me understand, I would like to ask a few questions. First, you mention that

I'd have wished they'd contact me about it instead, but as it's open source, they are of course free to use the code. I may need to make sure they don't reuse the name, though, so there isn't

Rune, The popularity of NanoVNA Saver continues to grow. I just saw this over on the NanoVNA-F user group. "We are currently modifying nanovna-saver (a good NanoVNA PC software) to fit NanoVNA-F, so

Thanks for the info Warren, 73 de VU2PGB VEEN

An update on dynamic range. In the photo the upper unit is the unshielded "worse" version and the bottom is the latest, best, shielded version. Both are calibrated for the 600 - 900 MHz range, Logmag,

is this modified software available to other users? Gyula

All, Thanks for the excellent information - so it does sound like step attenuator leakage is the culprit....which is not at all surprising given that it is a very cheap one ($40) that I purchased on

For those interested in the spectrum of the Si5351A here is a series of pictures, using my RFzero, at 267 MHz (i.e. 800 MHz "NanoVNA version"), 280 MHz, 298 MHz and 299 MHz. The pictures clearly show
