Re: Nano VNA Classic/H upgrade
#firmware
Hello Andy!
Have You driver for NanoVNA installed? Driver for H works with H4 too. Please not use driver from Windows. Vladimir |
Re: nanoVNA developers
Oy. TNX.

Re: Which Type of Jig?
I have understood that calibration with a jig in place moves the reference plane of the device to the ¡°business end¡± of the jig, so that it will be accurate despite the stray reactances of the jig. Is this not the case?

Hello jmr, Roger has shown a very good suggestion for a simple test setup. It's very easy to criticize something across the board without saying how to make it better. If you want to make *critical measurements*, like Equivalent Series Resistance, you should buy a device from Keithley. Rudi DL5FA |

Vladimir,
I got my new H4 in the mail today and seen that the firmware in it was old as well. When I went to upgrade it with the same process I got a new problem with the driver. the USB populated under the Universal Serial Bus Controllers tab and had the below items listed in the picture below. Is there a different driver process for a new to me H4? Thanks, |

I have tried to show jigs that can be easily built by members of this group. I find them quite accurate for typical measurements by hobbyists and hams. I will post some more test data over the next few days. I am interested to see what you recommend. Could you please show photos of what you built that can be replicated by group members and used with the standard firmware and apps like NanoVNA Saver and NanoVNA app by OneOf Eleven. Thanks - Roger |
Re: Which Type of Jig?
"I'm wondering what the advantages and disadvantages are of each."
In my opinion all of the jigs shown in this thread significantly degrade the true potential of the nanovna. They are fine if you just want to roughly measure reactance across LF through to VHF but they will significantly degrade the performance of the nanovna for critical measurements like capacitor or inductor ESR. |

There¡¯s a mistake in the map. The MEASURE entry, not BACK should be connected to the lower level. (one block higher)

Isolation?? These jigs are only used for S11 reflection measurements of components. When open there is a very tight dot on the right hand side of the Smith chart. Roger |
Re: Which Type of Jig?
I am curious. What is the isolation on these jigs with nothing connected?
The jig by itself and with the open connected. Thanks, *Clyde K. Spencer* On Mon, Sep 6, 2021 at 2:44 PM Roger Need via groups.io <sailtamarack= [email protected]> wrote: For measuring larger components below 60 MHz I use a couple of other jigs |
