I had the same problem Norton security deleted the file, I reinstalled it, Avast checked it and reported no problem.

sO ???

I think to remember that Zplot runs under Excel 97, so I searched the web and found a German website where to download . .

I did not have the time to try it.

This might help.

seems to me the vna saver is iffy,i get a smith chart with only the trace displayed ie none of the circle markings,its like the trace is in thin air,any ideas?,on my lappy the creed display just jitters all over,mentioned this a few times but lagley seems to be ignorred!
==========================

Paul,

First, I suggest calibrating your PC's display, for example:



Then, be aware that you can change the chart colours to suit your own taste. I found that the defaults weren't idea for me.

Cheers,
David

Hi Neb
i'm not sure i am the first to alert it, but....
somehow the link is blocked by Anti Virus , which states that this site or the file contains " a risk" while the browser tries to reach it.
it might that the site is the problem and not the content , but, is there a way to place it in other location NOT in this site?
it happens on old versions also.
usually , i "listen" to the alerts of the ANTI virus ( in this case it is ESET)
and, i , probably like others, would like to use this SW.

Larry,
ZPLOT uses VBA (Visual Basic for Applications) to draw its user interface and also do some underlying calculations. Other than AutoCad I don't know of any other applications that have licensed VBA from Microsoft for use as their scripting language. I suppose the VBA licensing fees are the primary factor

I did get sidetracked looking at the underlying VBA code in ZPLOTS. Some of the mathematical coding is educational for those geeks amongst us, of which I admit I am one.

Hi Kurt,
Free office has its own website:?
Too bad the free version doesn't run macros.?

Unfortunately, I have not tried to use zplot at this time but since Softmaker claims it is compatible, it may work.

Hi All
There has been several contribution on how to create a T-Check for the NanoVNA and I have made a document about why these T-Check are not so promising.
It is in fact not possible due to the lag of adequate error correct models as NanoVNA allows only error correction (at the best as the exact models are unknown) for one direction and not bidirectional.
Have a look and see the experiment I have made to enlighten the interested reader ?

Kind regards

Kurt

Paul,

Your description of the problem is vague at best. However, if you're saying that the display on the screen is the problem, it might not be an nanovna-saver problem
If I'm correct in thinking that the display is generated from the VC++ application mentioned in previous messages, then maybe install/re-install that App?

Ok.??
A quick search mentions Google sheets and IBM Lotus Symphony and a few others as alternatives.??
Maybe someone with experience using zplot can test it on the various free Excel alternatives and give the results here?? That would help other forum members.?

Definitely use N, not BNC. Mainly because BNC provides a less repeatable

connection, and for a VNA, you should be seeking the most repeatable
connection possible.

Hi,

nanoVNAPartner v0.17

What's new:
-S11 and 21 interchanged labels are fixed;
-S11 and S21 Min and Max points on Phase and Group Delay are added;
-Error on TDR when the main chart is cleared also fixed;
-Added auto line electrical length calculator using stimulus center frequency or lowest VSWR frequency.

If interested, may download it from here:

Kind regards,

neb

The Hugen photo, however, shows a circle fully inside the traditional Smith

My currently installed firmware allows changing scale of Smith plot, but not center.
Perhaps a firmware bug in October overwrote scale and offset...

Hi Rudi
The ZPlots has facilities as mentioned before to calculate Z0 as function of Frequency base on measurement of an open and shorted cable. Here is the result for the 33cm cable we are discussing. As you see there is interesting "bumps" along the frequency axe due to switching to harmonic modes for the NanoVNA
Kind regards

Regarding the impedance issue i did look at the phase oscillation from

phase oscillation was minimized. The return loss oscillation is not
changed by changing the Z0 but rather due to port mismatch.

Hello Kurt,

Thank you very much for your quick answer.

I have 3 questions:
1. Where did you subtract the length (20 cm) ?

2. Did you mean that the S11 phase oscillation curve (about sinus) horizontal center line
should be minimised to a straight line and not be bowed?

3. Did you mean with the change of Z0 to connect a resistor of 50 Ohm
at the end of the 22 cm coax cable? And then vary this resistor in 0.1 Ohm steps
to minimise the amplitude of the phase oscillation amplitude?

I mean your file "NanoVNA supplied cable 50K to 500MHz.png" in post 7877 at 2019-12-05 20:10.

In this screen shot there are 2 diagrams with S11 Phase.
When I try to get a similar diagram with a 30 cm RG174 coax cable with open end I get see attached screen shot nanoVNA-saver_RG174-30cm-open-end.png

Hi Paul,

if N is an alternative for you: N provides much better accurate quality for higher frequencies than BNC.

See pics:

The (slightly hot air bent) extended PE board permits hand isolation: Often a suitable balun for avoiding body ground errors is not needed.

Betreff: [nanovna-users] connector swap

hi all im thinking of changing from sma to bnc connectors on my vna,maybe mounted on an extender board hooked up to the vna with some small coax,is there any issues with doing this as regards acuracy etc,i assume using 50 ohm coax and re calibrating it should be ok?,any idea?.,cheers M3vuv.

What Linux distribution are you using?

As Nick said, if you follow the installation instructions, the program installs without a problem on Linux Mint 19.2 and works just fine.
