Hello dk1vi , Peaks occur because si5351 is w

I just had the same idea. Scan from 50MHz to 200MHz for example and the plots look good. Tomorrow I will inspect the PCB and see if all components are soldered properly. Ernst

Understood Ernst. Good observation. It will be of interest if other users report this situation. I assume if you do a cal that eliminates those frequency points, that is select a stimulus frequency

Alan, the peaks are always on the edges of the three frequency ranges 52k-300MHz, 300-600MHz and 600-900MHz. So I think it has somethoing to do with the timing of range switching. Probably the

Hi Ernst. I would check with care that the SMA terminations during cal are all secure. I would like to use a torque wrench designed for proper tightness for each piece. However, these connectors on

You may wish to check your sNp file. There could be an interpolation issue that is creating the discontinuity. I have seen such problems in "professional" SW like ADS and Microwave

Hi Alan, your plots look excellent, I wish mine would look same. The peaks are not related to the nanoVNA software V1.03. I see the peaks when I use the nanoVNA not connected to the laptop. Ernst

Good day, Ok, I just took a measurement after cal with the nanoVNA and then captured that data using their SW, There are two measurement .jpg attached. The first is their 50 termination after cal.

no the OP, dk1vi, has his nanoVNA. I am waiting on mine

You are waiting on the unit to be shipped. So I assume this is a measurement of another VNA using whose 50 ohm termination? Is the issue you are raising the software or the hardware? I can input a

this looks awful ! I am still waiting for mine to be shipped but this result got me scared/disappointed :-(

See my topic “inside views”. I’ve used a 300mah lipo battery, but is a bit large. Ordered and arrived from a near by store a 280mah wich should fit perfectly. Recomended size: 20x30 (max 45) x

Hi, got my nanoVNA today (black edition from banggood). Included was a set of cal standards: load, open, short and through with 2 SMA cables. As far I can judge, they are good quality. I measured Rl

Hey Hugen, I've been to your TaoBao site (http://gen111.taobao.com/), but even with English translation on the site/page, I can't figure out how to buy one. The shopping cart doesn't seem to work for

Tnx Larry! I downloaded 1.03 Next to grab a battery locally and install the boot switch. Mike -- 73, Mike, N1JEZ "A closed mouth gathers no feet"

Mike, There is a link in Hugen's threads that point to the new nanovnasharp version - he's writing it. As for a battery, I used an old Motorola cellphone battery from a RAZR and attached it with 2way

Has anyone got a source for the battery? Mine came without one. Also, I see a reference to vers 1.2 of NanoVNASharp. I have 1.01. Any link to a possible update? Does it require a firmware update to

Would you please post a link to that site. Burt, K6OQK

I bought the NanoVNA from elecdesign2015 on ebay and got the item pretty quickly, including battery and cables and short/open/load tests for under $60. The battery was charged. I'm able to talk to
