The 24 MHz clock in that NanoVNA product that this group is not about is likely used because it's easy to get a 48 MHz clock for USB from there. A simple frequency doubler can be used. The spec sheet

Thank You Raymond, I will try that.

Thank You Bob , I will try that.

Correction, the NanoVNA I have uses a 26 MHz TCXO, not a crystal.

I can’t speak to the designer’s original intent, but sometimes, you choose a starting frequency for other reasons. For example, you need to *program* the Si part before it can generate all those

Hi, Follow the instructions in the manual to put the NanoVNA-F in DFU mode. This involves pressing and holding the jogwheel or button while powering the unit on. The screen will be blank. On a Windows

I understand that the system needs clocks like 48 MHz (USB), etc. But in the datasheet of Si5351A, it mentions that, 1. Generates up to eight non-integer-related frequencies from 2.5 kHz to 200 MHz 2.

Is it a passive crystal or an oscillator? A passive crystal may still work fine, but some parameters may not be guaranteed for all parts. External oscillator will work over much wider range. 10MHz is

Normally, you don't need a working display for flashing. Read page 37, chapter 8 of the V2 user manual. It explains how to flash. If that doesn't work, have a look at the many posts in these groups,

Hello Raymond, How to recover?and and flash the NanoVNA?it will not turn on the screen is Dark, thank You

It works here. Thank you very much.

ISTR the latest is version 0.5.0 or so. Definitely nothing with a 4 in it. I saw it on the Sysjoint site the other day. Make sure to choose the correct device, apparently F V2. There’s also an F V3

Hi, You can search for it on Keysight webpage, I found it, but I don't know if link will work here:

Is there any way that I can reset the SYSJOINT?NanoVNA-F V2 to it's original firmware setting, Thank You

Yes I believe it is .4 for the?NanoVNA-F V2?according to SYSJOINT

Did u upload the correct FW for the specific VNA ?? [email protected]> wrote:
