Oh, I forgot to include the link... http://yatrim.com/? The author also has an Android utility to flash over Bluetooth for those that have added the BT serial module to their Nanovna.? Again: the

Interesting. As a digital guy, I'm surprised a 6ghz instrument can use an Si5351 as the primary clock source. Rather high jitter, SiLabs has far better. He has two 100mhz channels from the Si5351

Folks, I use my LG gpad for quite a lot of my activities so I started to search for an Android app that could flash and read the Nanovna firmware using the USB OTG function. I found 'STM32 Utils' and

I add Serial connection support to my firmware (can use v1.0.39 from here /g/nanovna-users/files/Dislord%27s%20Nanovna%20-H%20Firmware): You need select CONFIG->CONNECTION->SERIAL

dB is a way to expresses power loss or power gain. For power loss, the formula is 10 x LOG (one power / another power both in Watts). If the voltage is known for the same case the formula is 20 x LOG

You can check my last firmware v1.0.39 /g/nanovna-users/files/Dislord%27s%20Nanovna%20-H%20Firmware Added fixes for this compensation (thanks for OneOfEleven), but extended for use

Hi, I have the nanoVNA2. I'm trying to measure the loss in db between the two ports. I have the manual but it has nothing on setting the device up for S12 port loss measurement. The manual just tells

Hi BruceN, Which entry do you not understand? I can’t help anyone who doesn’t know how to read websites. Anyone who reads will know that there is firmware from multiple sources on my page in the

There is also a version of LTSpice for Mac OS/X. The menus are pretty non-standard, but the program is solid.

It could be a NanoVNA-H v3.3 by Hugen. He did make some in the "sandwich" style before he used plastic cases. BTW - from the picture it looks like your battery is swelling. If so time to get rid of

All Nanovna 1st iteration devices , including the H are all essentially the same and can use the same firmware.?The newer unit is the H4 and the F, both which use different processors and different

Look at the attached photo.... on the back of my 2.8" nanoVNA you can read "NanoVNA", but on the PCB it is clearly readable "NanoVNA-H", followed by the version number 3.3 So, is my unit an -H model,
