Hitting the sweep button gets me an error "Failed reading data 0 10 times". My firmware NanoVNA-H v1.1.0 maybe is out of date. I am using 2.8" SeeSii NanoVNA. I am pointed here for updates

Sounds plausible to me. I have done it hundreds of times, tuning my 2m/70cm antennas before shipping. Every time I run the 420-450 scan, I have to reboot the VNA to get accurate readings on the next

I think those who have been around longer, find the better sites for documentation. When they are posted, GREAT! A side issue to this quality/source, can be the QUANtity/source. I.E., I used to

I wonder if it's the result of an inconsistency in how the multiple sweep ranges interact with the discontinuity when stepping across the harmonic boundary. Both NanoVNA and NanoVNA-Saver do linear

Good afternoon, I have had the same experience. I have t to calibrate and save the calibration for the exact width I am looking for to one of the memories. Then, after scanning with one of the

Not necessarily - there are USB hubs that if they get a request for high power, and can't supply it, just shut down the power and disable that port, other than some microamps to tell if there's a

Good plan; now execute it and you should be all set!

I am not really sure what kind of problem you are running into....( did not bother to read) But if it looks like a software issue, smells like a software issue and quacks like a software issue, but

5v power should *always* be available on a USB port, so slow charging can happen even on a dead device. What is negotiated are faster charge rates, so, as you noted, a dead device will need to slow

Up front - few years back I got involved with nanoVNASaver and soon realized this is not a right group to ask about nanoVNASaver software. BUT - if there is a remote possibility that has changed Does

I was going to quit this thread, but... I left the nanoVNA running overnight , connected to my PC and I did "shutdown" and turned the PC power source off. Turned off the D_link power source too. In

The OS still controls (or at least manages) the hub's power as part of the whole USB tree, even if the hub itself receives external power. That is, the hub can decide if it wants to turn power on to a

Interesting question. I mostly use my Nano VNA on HF bands. It has never failed in any aspect - one port antenna, 2 port filter tests, over all of the HF bands anyway. But when I did the 440 band

My PC is "open architecture " ASUS motherboard in old desktop case. nanoVNA USB port is via powered D_Link " USB hub. It has not been powered for about 6 months ,,,, I am going to let it fully

I charge my NanoVNA from my PC's usb port every time I use it, work fine. Are you using a laptop, or a tablet maybe? N0NC

Or it's not responding to the request for more current.

ask and yea shall receive the original post answer in in the manual under Specification and that is why it won't work - in theory Supply current 500 mA NO CHARGING Battery current charging 1.2A NORMAL

This make no sense you pause the sweep, or after a single-sweep, the LED is steady on. hence there is no flash ? DO I understand this correctly ? Calibrated and maybe even not calibrated (?) nanoVNA
