I wasn't able to get the mac version working - I could trace the curves, generate the data and plot the graphs, but it won't generate the models because the program asks for m4 - which it appears requires some fairly dedicated work to install, including the mac developer tools. (near 5gb.)
Not in the mood to install 5gb of mostly unused data on my hard drive, I opted to use the windows version instead, which has so far gone a lot better. I can generate the models without a problem.
I would ideally like to do some modelling in Paul Falstad's java modeller app. This app requires mu and kg1 data. Is there a way to output "mu" and "kg1" numbers from the curve captor data?

GNU m4 is an open source macro processor. It is kilobytes in size not GB. Yes you can get it as part of some huge package but Google will find m4 for you.
xCode that includes m4 is on your Mac OS X instal DVD. It is certainly smaller than 5GB.
I've tried downloading m4 from here: Index of /gnu/m4
But can't seem to get it compiled. (I am no unix expert.)
What I was trying previously is to install Vink, and to install m4 via Vink. Vink requires Developer Tools to install on Mac OS X.6. Developer tools is $5 in the app store and appears to be 4.24gb.
I'm sure there is a way to get the m4 package to install, but the windows version is a significantly easier option at this point.

Joshua - you have to import a .gif file (showing the tube curves) then you have to define the volt axis, the current axis, and the grid curves, all at respective voltages / mA. (There is a drop-down menu for each item and you can set the increments.) once you've done that then it becomes simpler.
Thanks.
How do I get the tube curves .gif file, by screen capturing the tube's data sheet?
Edit:
Also, can the software create tube curves from numerical data?
I do a screen capture off of a PDF of the tube datasheet, usually downloaded from Frank's web page. Save it as a gif file.
If you can fake the number format this program makes from the point plotting of the data sheet curves, I suppose the program will accept it. That implies that you're getting data from some sort of digital curve tracer, or maybe just reading them off a scope screen and then typing it in.
Curvecaptor
Hi ,
I have downloaded the CurveCaptor 0.9.1 an then installed it, but after excecuting the command m4.exe, appears a DOS windows.... Now What ??
Could anybody say me where to find some basic "How to Use" guide, please ?
I have seen the trhead, but I can not found information about that.
Many thanks in advance.

Hi,
I'm not familiar with the Windows version but I do use curve captor alot on Linux. Maybe I can be of some help. m4.exe isn't the executable to start curvecaptor. m4.exe is for the tube model macros. There should be a TCL script that was installed called "curvecaptor" or "curvecaptor.tcl". That's what you need to execute to start curvecaptor. Did you also install TCL ? Curvecaptor requires it to run. If not you can get TCL from here.

I believe I read somewhere that on Windows you also need to install m4. You can get that from here if needed
m4 for Windows
Documentation on curvecaptor seems to be hard to find. I did come across a tutorial a while back. Seems to be gone from the internet so I included a copy in the attachment.
I cant seem to get usable data
Hi,
I am trying to build a model for an 812A Triode.
I have followed all the instructions I can find to build the model, however
once the devcie model is drawn, some of the curces are dropped, and what remains is an incredably bad fit. In addition all the Loren modle did not compute #INF mA
Here is the curve I am trying to fit to as well as my captured data set.
I would be greatfull if somone could give me some pointers?
I have renamed the .crv file with a .txt extension to allow it to be attached
Regards
Roger

Hi Luis and Andrei,
My computer run on Windows XP and I like to use this "unique" software !
I download the files and find out they was only C source codes ... Can you tell me what compiler I need for those files and where can I get it.
I look at the freeware GNAT GPL 2011 from Adacore but I don't know if it is a suitable compiler for that. I work with Borland C and C++ compilers many years in the ninety's and I have good programming knowledges but many new things happen in this world since.
Cheers,
Alain.
P.S. Is it true it work only with diodes, triodes or pentodes "triode connected" ?

Ok ...
Forget my question, I found out how to do ... ActiveTCL Community Edition ...
I am dowloading this free software right now, it is a kind of "source code interpreter", like for the old "Basic files" ... No need for a compiler ...
I will also download the Crimson Editor ... It suppose to be able to edit the TCL / TK files and many others programming languages ...
Cheers,
Alain.
The software is writen using BOTH "C" and "Tcl/Tk". You will need a c compiler and tlc/tk. As for a test editor, if you have MS Windows then you already have notepad. That will work.
I have tried several times to get curve captor working on my Linux box without success. The Tcl part is no problem. My main problem is compiling the tubefit.c prog.
Any tips for getting this going?
Cheers
Ian
There was 3 files zipped, the "curvecaptor" file codes really all look like C but I think Tcl is some kind of C ... I can read it all with any text editor but the Crimson editor I download yesterday is very good, all the different kinds of code have different colors.
The "models.m4" file is a "macros" file used by the compiler or interpretor and the "tubefit" file just look as a binary datafile ...
I will have to study a little bit the Tcl language to understand all the codes, it is slightly different from the old C and C++ I use to work with, for example, all the procedure names are preced by the "PROC" keyword like in the Pascal language !
But all informatic languages have a strange likeness, I work with about ten of them in the past and I can learn one more for sure ...
Cheers,
Alain.
