NanoVNA V2 - I vote for a larger instrument...

Burt K6OQK Member Profile All Messages By This Member #3454 Once again, I vote for a larger version. As I said earlier, I would like one to be tablet size and with Type-N connectors. I suspect that I'd probably be willing to pay a fair price for a larger, more robust instrument. I typically use my RF test equipment of this type in the field, rarely if ever up a tower, often at the tower base, not so much on the bench. I want something I can easily see and use a touch screen that works with real fingers, not fingers I have to first stick in a pencil sharpener. The idea of using the nanoVNA in conjunction with a phone for a larger screen or a tablet for a tablet size screen does not appeal to me. For me, a VNA is a tool, not a project - making an antenna work properly is the project.

Bo, OZ2M All Messages By This Member #3456 Hello If the list owner could open a poll, already a tool in groups.io, I will be happy to vote for my v.2 preferences. Bo
Burt K6OQK Member Profile All Messages By This Member #3465 By the way, for my needs, I would like an instrument that goes from 100 kHz to at lease 1 GHz.

M Walter All Messages By This Member #3470 Perhaps the solution is a tablet that run nanoVNAsaver. Larger screen, reasonable touch sensitivity so we don't have to sharpen finger. (Ran a finger into table saw 10 years ago: don't recommend it) Just received my nanoVNA yesterday. Scrambling around looking for connectors and adaptors. My immediate goal is to measure components/filters. Awesome little device. Mark Walter
Paul Brodie All Messages By This Member #3472 Nothing wrong with "N" Types, But how about TNC... According to Amphenol and RS good from DC - 11Ghz. And a better size for small VNAs. Paul
Oristo All Messages By This Member #3522 Edited I wonder how many actually wants a small form factor. Me, for one; * not much space next to PC keyboard * hands are usually full when going to work elsewhere, making pocket-size VERY handy. * with more secure connectors, I could hang small, light, wireless nanoVNA V3 on e.g. antenna connector, then access UI from smartphone (carried in belt pouch or another pocket).
Mike N2MS All Messages By This Member #3540 I would like to have the option of controlling my VNA via a smartphone or a tablet. I believe this is the way the industry is going for portable instrumentation. I saw two examples this summer. The Army Corps of Engineers is surveying the beaches here in New Jersey for coastal erosion. The GPS receiver is mounted on a pole with the antenna on top and the data was collected on a tablet. This remote interface was handy because the receiver mounted on the pole had to be placed in the surf. I had a service call with Comcast to replace a faulty cable box. The tech used a test set which was controlled and monitored with his smartphone. He used it to check signal levels at various points, some with were tight and he could analyze in a comfortable position instead of crouching down. The MetroVNA and Sark VNA have bluetooth, it shoulc be included in the next version of nanaVNA.

Jose Luu All Messages By This Member #3548 As for remote control via smartphone, a simple way to do it would be to leave the USART2 pins available for external serial connection (that is PA2 and PA3), from there, an external additional bluetooth serial adapter (HC-06 for instance) would make the commands available to a smartphone. Currently PA2 and PA3 and used for the switches, but I can see that other I/O pins are available. toggle quoted message Show quoted text On Mon, Sep 30, 2019 at 10:05 AM n2msqrp <mstangelo@...> wrote: I would like to have the option of controlling my VNA via a smartphone or a tablet.

I want something I can easily see and use a touch screen that works with real fingers, not fingers I have to first stick in a pencil sharpener. The user base does seem to be split into two. 1) Those like you and I that want to use the instrument outside and want a large screen to make it more usable. 2) Those that want to use it as a lab instrument, and so don't care too much for the screen size, as they will use a PC. The idea of using the nanoVNA in conjunction with a phone for a larger screen or a tablet for a tablet size screen does not appeal to me. Same here. For me, a VNA is a tool, not a project - making an antenna work properly is the project. Yes, me too. But for those that want to use it in a lab, things are quite different. Burt, K6OQK Dave G8WRB
[email protected] #5068 What I want is a slightly larger display, a 3.2" or a 3.5" is not that much more expensive... But I also know: the most dangerous thing in the world beside a programmer with an soldering iron is a user with an idea...

[email protected] #5195 Thank you for the link.The NanoVNA-F seems like another great device, but the larger screen is just a small wish, I'll keep the 2.8" for now. I more or less tried to make a point that it is not possible to listen to every user.
