I wonder/hope that will there be a TDR in next VNA the 2.0. Delay gives a good starting point for cable compensation, (which people here will probably know better than I)I mean the one with upper frequency of around 3GHz.
Regards

Interesting link and I found the EM simulator link there also. I have to calibrate my VNA to 900MHz maybe I get better results then.
I wonder if VNA 2.0 has a HW TDR also, or is it a SW feature.
Thanks

========================================================
Dale,
Both Gabriel's V2 device and the new NanoVNA-H V3.4 have faster processors and more flash memory. The faster processor should translate to faster sweeps although no one has confirmed that. Also, driving the larger 4" screen may eat up the gain in speed.
Gabriel's V2 device will increase the number of on screen data points to 201. But both developers are probably wary of breaking compatibility with current software, all which expect 101 data points to be returned. I'm sure the firmware and software developers will figure out a solution.

By any cgance was it the one shown below? I got this from:

I believe a Gabriel mentioned that acceptable performance was currently topping out at 3.2 GHz. Might be a stretch to squeeze another 300+ MHz out of it.

SimpleUsbTerminal so I found it on Google Play Store and installed it on an Android.
I was able to set it for 9600 baud, and it found my NanoVNA as a USB
device but didn't have a driver to connect it. It reported vendor ID 0483 and
product ID 5740, but that's all it would do. On my Android, here is an app that works, using its CDC device setting: Another Play Store app that also works, without the need for device setting:

Re: How high will Hugen v3.4 HW go?
I agree with Larry on this one with the exception being if design changes
now end up delaying the unit a while but the performance is greatly
improved I would prefer to wait. As one that has been spoiled by "real"
VNA's.

I just tried jackpal Terminal Emulator for Android. It seems to be only an xterm window to look at the Android system directories. I already had Termius, mentioned in the posted article of "Top 10 Android SSH Client ¨C Best PuTTY Alternative for Android", but it only works as an ssh client. There is no menu to connect as a COM port. SimpleUsbTerminal so I found it on Google Play Store and installed it on an Android. I was able to set it for 9600 baud, and it found my NanoVNA as a USB device but didn't have a driver to connect it. It reported vendor ID 0483 and product ID 5740, but that's all it would do. I can solve most problems with PCs but troubleshooting apps on Android isn't for me. For now, I'm happy to know about /g/nanovna-users/files/NanoVNA_Console_Commands_Dec%209-19.pdf that @Oristo mentioned.

===============================================
I'm sure Gabriel does not need to be reminded of "Time to market" as her V1 VNA never saw the light of day because the NanoVNA hit the market before she could finalize a production unit.
Her V2 VNA should have a little bit more breathing room because no one else has proposed a 3 GHz unit at her cost point and design specifications. She has said development costs are being funded by a third party whose only stipulation is that the project be open source. That's a rather strange business model unless the third party has deep pockets and is backing the effort as a service to the community. Usually a project of her size is profit driven with at least some anticipation of return on investment.
Still if the H4 4" is any indication, 2020 shapes up to be another good year for those of us who have benefited from these innovative and low cost VNA designs.

Re: NanoVNA-saver 0.2.2. crash
I am going to try Lucio's suggestion, to "uninstall" V0.2.2. completely. As I did have V0.2.1 on my W7 computer when I rolled V0.2.2 into the same directory.
In the mean time, I am going to take a break from my "toys"
I'll be lucky if I quit by 9pm today..
Perhaps wait for V0.2.3 as Rune was looking at issues.. (Thanks By THe Way)

Re: How high will Hugen v3.4 HW go?
Yes, Gabriel needs to lock down her design ASAP.
That little thing called "Time to market" can be a killer if you wait too long.
She has already made the schematics available and any unscrupulous vendor can begin to lay out boards, wait for the firmware to be available and push out inferior unauthorized copies.
