That URL involves neither JavaScript nor cookies.
It is my first CSS learning exercise and certainly buggy.
For example, branches wrap badly on narrow displays.
It displays OK on an iPad, but hovering requires a mouse..
Hovering a mouse pointer over some text boxes should pop up tooltip hints.
Underlined TEXT have hyperlinks to longer descriptions
in a plain HTML text file on the same website.
TRACE and FORMAT entry annotations are yet to do.
I will also investigate iPad support..

Terrific addition to our knowledge of the NanoVNA.
Thank you very much,

Looks real good. I think it needs a button to get you back to the main page. I guess the browser back is the only way to do that
Thanks

Hi Oristo
This looks great! Really helpful.
I have spotted a couple of differences between it and what I'm seeing with
the 2 trace antenna analyser firmware on my Nano. I believe the 2 trace
version uses a clearer larger font, so the format menu structure is
slightly different.
Here's what I'm seeing on my Nano:
The Trace menu only has Trace 0 and Trace 1.
The Format menu ends with "More" directly after "SWR". Clicking the "More"
button brings up another menu with "Polar" & "Linear" on.
With "Reference position" my default setting is shown as 7 000 for LOGMAG
and changing it to 8 000 moves the trace reference (shown by a small marker
at left of screen) up one grid space, to the top of the screen. With SWR
the trace is off the bottom of the screen when 1:1. Changing the reference
position to 180 brings the trace up onto the bottom of the screen.
Regards
Mike

Hi Mike - I have spotted a couple of differences between it and what I'm seeing Thanks for feedback; content is updated:

Wow, quick update Oristo. Lets hope none of the other builds aren't
different!

Lets hope none of the other builds aren't different! That menu is updated to correct link bugs: Its associated help file has been improved but not updated to address functionality added since "original" firmware; Additional software and firmware description:

I am preparing an updated menu annotated map,
based on attached menu screen shots, of which I captured 15.
Let me know if I missed any or have suggestions
e.g. for improving annotations of unchanged menu items:

@Oristo
The help file refers to quadrature sampling done with the SI5351 and the two SA612.
This is wrong. Some of the references go to IQ downconversion for SDR but the nanoVNA works differently
The two SA612 convert two uncorrelated signals ( the bridge unbalance and the power reference) to the 5kHz IF frequency send to the adc's
The DSP does quadrature mixing down to DC so there is no mirror signal to suppress
|
Hi Erik - Thank you! I have not yet looked at nanoVNA firmware and supposed more similarity to SDR than evidently exists. The DSP does quadrature mixing down to DC
so there is no mirror signal to suppress I need to do homework here: * do SA612s not feed I and Q into ADC? * does not mixing always generate sum and difference frequencies..?? sin A cos B = (sin(A + B)+sin(A - B))/2

Indeed. Two separate signals. For IQ mixing the LO inputs would have to be 90 degrees out of phase and the input must be the same. Both are not the case. The nanoVna needs to measure two independent signals at the same time. Actually three. But the adc is stereo so one input is switched between reflection and transmission signal * does not mixing always generate sum and difference frequencies..??
sin A cos B = (sin(A + B)+sin(A - B))/2 Indeed. Here the difference is zero e.g. DC and the output is averaged which is a very effective low pass filter so the sum at 10kHz is eliminated No need for other filters

Annotated menu map for updated firmware, take 1:
* broken branch FORMAT->LOGMAG requires CSS fix, may take awhile..
* links and help text not yet reworked..
I mainly want feedback about missing menu branches and/or leaves
Does anyone know why ELECTRICAL DELAY is under SCALE
instead of e.g. CONFIG?

I think on the CAL line, reset should be the very first item opposite CAL and everything else is below. Why? You need to do a reset before you do the rest of the cal steps.?
Leave 'calibration' at the bottom as you rarely use it.?
Also, as soon as you press Done, you get the save menus, no?
There is one more entry after the DFU button
That's it for now. Looks good!

Hi Larry - I think on the CAL line, reset should be the very first item opposite CAL and
everything else is below. Why? You need to do a reset before you do the rest
of the cal steps. I totally agree and can rearrange that on the tree.. Leave 'calibration' at the bottom as you rarely use it. Actually, I calibrate pretty often, nearly every time before measurement, to consider everything except DUT as "ideal". Also, as soon as you press Done, you get the save menus, no? Yes, but my CSS is not good enough for two branches to SAVE .. but I can duplicate SAVEs! There is one more entry after the DFU button I see only BACK and do not bother mapping those. Thanks for the feedback!

When you click the DFU menu button, you get the next menu with 2 items: Reset and Enter DFU and Cancel.? The full word:. Calibration is a switch that can be inverted text to show calibration is being applied, or normal text to show calibration is not being applied.? How often do you turn it on or off???

I wanted a printed chart that I can hang on my wall so I changed the color scheme. I hope there will be no objection to me sharing an ink-saving chart.

Hi Larry - When you click the DFU menu button, you get the next menu with 2 items:
Reset and Enter DFU and Cancel. OK, I never dared press DFU and anyway added a slide switch for hard DFU, too often required for hangs.. The full word:. Calibration is a switch that can be inverted text
to show calibration is being applied,
or normal text to show calibration is not being applied.? OK, I see "CORRECTION", not "Calibration" How often do you turn it on or off? Maybe raw data helps understanding impact of shielding and layout changes?

Yes, I meant correction.You have a save menu after the correction button.. shouldn't be one. Correction is on or off.I still think reset should be at the top of the list and save after calibrate steps.?
