Hi Sam,.?? I spoke to Dennis about this earlier as it's been this way for all of his larger font releases.? Unfortunately, there is only so much room on the display and Dennis is trying to squeeze

Hi Kurt, hi David, thank you very much for your replies! of course, the coax cables were calibrated at the far end with SOL isolation and through. The first calibration (picture 1), directly on CH0

I use Ansmann cells in my other projects. https://www.ansmann.de/en/rechargeable-batteries/lithium-battery-18650 Can sustain 2C charge + has battery management included. At worst case in a Nanovna,

I noticed on my unit the larger font is clipped at the bottom of the screen and at the top right. Is there a way to change this? Sam W3OHM

I got one also, as time passed I thought it wasn't coming but it just took 2 months. I ordered something else that came much quicker and I noticed on the tracking that it seems like it's the time of

Hi Norbert If I understand you correctly you calibrated the Ch0 port directly and then just connected the various cables to Ch0 port and terminated at the far end with a female 50 ohm load. If so it

How have you terminated the coaxial cable length under test? Just measuring S11, I would not recommend using Port 02 as a termination, but, rather, the 50-ohm SMA cal standard. The impedance of Port

Hi Andy That's 1.625C. Exceeds spec of 1C max. Bad mojo. Please try charging from a USB2 standard port and measure the current. Something is limiting the current given that you were using a 2.1A mains

FYI, bought one of the 'deal's ($21), from ebay. Got a tracking number and was told it had been shipped. Never arrived so i contacted the seller and got no reply. Ebay got involved when i contacted

I would suggest that with the NanoVNA being already such a low price, there is a cost to one's time and effort to engage questionable vendors or potentially faulty or misrepresented products. While I

My opinion aligns more with David. The basic question is if this is a product support group or a private group for developers or otherwise includes proprietary information. If this forum is only for

Hope it’s not old news, but I just ordered one at Walmart.com for ~$38.

go to walmart .com you get it there for a couple bucks more 3 day delivery and ou know you haven't been scammed. But also, read the fine print because you only get bare bones, no cables, no

Dave, excellent information. I have 3000+ purchases on eBay. Lots of items from China. I always do as you suggest, check the Seller's Feedback and number of sales. Just one last thought...…

For those that want to experiment with a nice tool to add/remove transmission/coax line impact there is this very advance excel tool https://ac6la.com/zplots1.html#Overview It requires excel from

Hi all, today I performed a NanoVNA calibration test to find out if the coax cable length and quality has any negative influence specially on the S11 return loss. The calibration setup is 10kHz-900MHz

Simulated port extension methods,: 1. 1 - 500Mhz sweep shorted RG-58C/U (Belden 8262) 2. subtract ideal coaxial line 3. subtract datasheet loss data coaxial line 4. subtract datasheet loss data

As this ("deal on ebay") has been a recurring theme for some time (these sorts of offers happen on other items, nanovna is one of the subject items for this sort of spam/scam), I would like to suggest
