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

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

Hello! Just wondering if anyone is offering a unit currently being sold that goes up to 6ghz? I'm on OwO's notification list, but theirs doesn't seem to be in production yet. I'd like to purchase

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

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

"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

Perhaps, but not at all consequentially at 60MHz and below, IMO.

Which fixture? SMD or Box? Lead length of test component, cal loads or fixture itself? Roger

I think that the lead lengths on Roger's fixture could be tightened up quite a bit. 73, Don N2VGU.

There’s a mistake in the map. The MEASURE entry, not BACK should be connected to the lower level. (one block higher) Gene – K1AVE Sent: Monday, September 6, 2021 3:51 PM To:

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

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* [email protected]> wrote:

Thanks for the reply, Vladimir. Yes, I was able to fumble my way around and did in fact find that at the time of writing my first note I didn't have the firmware installed right. I was able to get

For measuring larger components below 60 MHz I use a couple of other jigs which work quite well. The first one is built with off-the-shelf cables and a BNC to banana jack adapter. I built a version in

yeah, but the "shortening for resonance" exists even if there is no "end insulator" (example is a rigid rod). Schelkunoff is talking about a *model* for the wire antenna that would be simple to
