26 : Correction of Maxima Version and "Unpacked" DERDEI Code

- also @Jose Luu : /g/nanovna-users/message/3278 -

Hello,

Allow us, please, to inform you that, as we already promised at:

21 : The Mathematica Code and the Unpacked DERDEI Code :
/g/nanovna-users/message/3290

we just uploaded the new, "unpacked" version of DERDEI at:


Also allow us, please, to inform, facupov, the interested
Common User that in order to avoid unnecessary
complications, he has to take into account the following:

Re: [Maxima-discuss] Maxima 5.38.1 64 bit build Windows
From: Gunter K?nigsmann <gunter@pe...> - 2016-06-14 06:44:35


the version 5.38.1 of [maxima] requires a bunch of hard to
follow instructions for installation under wxpp32 or wxpp64.

Therefore, we * e r r o n e o u s l y * suggested, what we had
avoid to say, about this installation at:

2 : yza, Sep 21, 2019 : /g/nanovna-users/message/2802

and thus he should install the last * f u l l y * working 32-bit version
5.36.1 of [maxima] with [sbcl]:



We are terribly sorry for the inconvenience.

Please accept our apologies.

(0.b/b) Note: He may need to also do the following:

|Start|Settings|Control Panel|System|Advanced|Performance|Data
Execution Prevention|(o) Turn on DEP for all programs and
services except those I select:|Add|{X:\}{wxpp32}Program Files\
or{wxpp64}Program Files (x86)\Maxima-sbcl-5.36.1\bin\sbcl.exe|
|Open|

(1) He should unzip [DERDEI20191001.7z] to the default
folder with name: [DERDEI20191001], in the root folder of a drive,
which, if it is different than of our [K:], lets say [X:], then he has
to edit [DERDEI-unpacked_20191001-600-1000.MC] and
in the multi-lines beginning with /*10*/ up to /*15/ to replace
every occurrence of K: by X:

(2) He should skip | ignore any instructions given in the
Documentation:



regarding the file: [functions.txt], because all the contents of this file
are now embedded into: [DERDEI-unpacked_20191001-600-1000.MC]
at the aforementioned lines, and thus he should also ignore
completely the file: [useless-MC-embedded-functions.txt],
which was included into [DERDEI20191001.7z] just for the shake
of completeness

(3) He may execute sequentially, the 15 multi-line commands by
Copy-Paste into [XMAxima] and Enter them one-by-one

(4) He may omit the just informative multi-line commands
beginning with: /*2*/, /*4*/, /*6*/, and /*8*/

(5) If he likes, then in just three 3 steps he can: (I) copy
the whole content of [DERDEI-unpacked_20191001-600-1000.MC],
then: (II) paste them to [maxima], and finally: (III) run it fully.

(6) He may want to change the way in which the six 6 graphics
windows are presented by [gnuplot] and to select between the
"cascading" way, in which each window has to be closed, in order
to appear the next one, or the simultaneous one, by following
the instructions provided by the [Maxima 5.36.0 Manual: 12.
Plotting][12.3 Functions and Variables for Plotting][System
variable: gnuplot_view_args]:

"In Windows versions of Gnuplot older than 4.6.3 the behavior of
"~s -" and "-persist ~s" were the opposite; namely, "-persist
~s" made the plot window and the gnuplot interactive shell
remain, while "~s -" closed the gnuplot shell keeping the plot
window. Therefore, when older gnuplot versions are used in
Windows, it might be necessary to adjust the value of
gnuplot_view_args."

(7) If he is indeed a [mathematica] user, then it is up to him to
transfer -more-or-less "easily"- the graphics commands in the
remaining just four 4 [maxima] multi-line commands beginning
with: /*3*/, /*5*/, /*7*/, and /*9*/, to [mathematica], because:


"Macsyma" [maxima] "was revolutionary in its day, and many later
systems, such as Maple and Mathematica, were inspired by it"
-
at least, if not much more, more than that...

Sincerely,

gin&pez@arg

This was a little unclear to me, but interesting.? Are you saying that
you used the 51 ohm resistor held by the jaws of the alligator clips for calibration?

? Then the data you posted was for that inductor?

Bob,You don't need a torque wrench for this device - it's just not that

were

discussed a couple of weeks ago. Also, take the front cover off the

display

and ensure that the SMA PCB mounts on that side of the board are

soldered.

Most aren't.

I was ready to order a different unit from a different vendor but that
doesn't appear to be necessary. I am going to shout from the rooftops
about this great instrument.
Sure it has its limitations but is wonderful nonetheless. I am getting
displays that, while not totally in agreement with my other gear, still
look very believable. Even the shape of the SWR vs frequency curves are
similar to my fancy VNA. And with the help of the sharp program I can
print results.
I am still learning about saving and recalling and such. I have some SMA
hardware on order that will simplify some of my testing. I am still
agonizing over the cost of a torque wrench; so far I haven't gotten one.
Another impressive characteristic is the accuracy of the frequency.
Putting it into CW mode generates a solid, precise signal. I wonder

about

the amplitude; I will see about measuring it on my SA. Perhaps it will

do

as a signal generator. It's well shielded, as I can't hear its signal

with

nothing connected to it.

Bob,
If you ever decide to upgrade your firmware you may run into something
similar. My second NanoVNA arrived with only the 2 trace firmware
installed. When I tried to upgrade to the 4 trace firmware it wouldn't
take correctly. The solution was to first install CLEAR_MEMORY_DFU and
then install the 4 trace DFU. Its not always necessary, but I now use it
as a matter of course to prevent artifacts left over from the previous
install from causing hard to track down problems.
