Hi Rune I would not expect measurements made outside of the frequency range of the current calibration to be "accurate". I would not want nvna-s to change the sweep setup when a calibration is loaded.

Many people report work that’s in progress, but report it in a way others can at least see what is the aims of the work. The title should give some indication of what the work is about, but even

The IP5303 inverter section is running at 350KHz when running off of the internal battery. That will create a pile of noise. For a good sense of supply line noise, the IP5303 needs to be

Hi Rune, OK, so this this may just be down to terminology after all. I guess what I'm looking for is something like the marker information presented in the AIM VNA software (see attached). Having both

From: ambaer52@... I understand that there is a 4.3 inch version available. Has anyone purchased one? If so, I am in the US. Where is a reliable source to purchase one? =========================

When @edy555 designed it and in Japan it was possible for others to build it in kit form, then in 2017 a description of the structure was made. At the end of this description is a list of known but

The Antenna Analyzer made by EU1KY was further developed by Ian, KD8CEC, it used a similar calibration solution here. It is important for L / C measurement when you use open, short circuit, and load

Using some generous amplification after the 2GHz filter the nanoVNA performance for S21 measurements is getting to a usable level. Attached S21 of a 2GHz cavity filter. It proves the SA612 has a lot

USB power is very noisy. Hugen79 designed the power part of nanoVNA different from edy555 Hugen79 uses the output of the IP5303 for 5 volt where edy555 uses the USB power. Did not check noise on

The xc6206 is terrible in transient response. Max input voltage is 6 volt so I use only 5 volt from linear regulator. The SA612 can have up to 8 volt but no big gain in performance

Yes.

May be the compilation problem caused by the flash usage limit, I have re-compiled after removing the sin/cos table in my firmware, now it can connect to the web interface normally.

Hi Rune ,thanks for your attention. the feature of recalling CALIBRATION file changing the settings of nanovna is usaul on vna I used at works for some year. The calibration is valid if you don't
