content: Hello alland sorry for my bad englishi got a question and a i need some help !!i did some research about curve tracing using a x-y mode on oscilloscopes and i know about curve tracers like octopus and cheap simple stuff posted on the forum or else where sound card based curve trackers like the one by Dr gorge e steber if i remembre and redpitaya opensource multi function oscilloscope etc ... and curve tracers posted on magazins like transistor curve tracer on i cant remebre name of magazins it was an edition of 2009 and i saw posts about the guy who is solding his what he calls "my intellegent curve tracer "and i have dual curve tracer a old analog polar t1500 and i found that there is a new equipementinvented heuh not invented but produced by a company on turkey its a fados 9f1whats diffrent between a normal curve tracer and this equipement is that :1- it hase a simple usb based oscillscope with 2 inputs2- is that the software make a comparaison mean that if you have a 2 identic boards and one of them is working you can take mesurment of the first one store them on the a software and then if you wanna compare the broken board to the good one u just call the file and start automatically stepping from point to point and if it find a diffrent on the curves it say there is a error herea good idea not new but simple and cooolwhat is my question is that is there anyway to i dont know mod the wildrange of opensource software online to add this methode to one of them i tried to do that on a ready made projectbut i failed guess its not that simple for a newbie like methe code was hard it was coded with cand it stores the curves as cvs file and then you can load it but i wanted todo a sequence comparaison but i failedto make it a first short post ill put a link to the fados and to the project i wanted to modifynote im poor cant by a huntron or a fados im from morocco and i fix laptops for livingso imagine the time i consume finding one fault on a 50 page laptop schematic pdf !!!!here is a discussion between me and the owner of the opensource oscilloscope projectYassine,Thank you for your interest and kind comments.A curve tracer could be added and connected to the scope. Since it is hooked to the computer, it is easy to save data. Perhaps another software could do the curve comparison. It certainly would be easier to compare the data output in a spreadsheet or math package. But certainly, I'll add the feature request to the list.Also, thanks for the offer on translating. I'll take you up on it when I attempt to incorporate translations.Have a great day!Jonathan--Jonathan WeaverKM4FIKhttp://jonw0224.weebly.com/hi brother i was missing with your code a littel and i find out that the compare function will be easy but need to much coding basically what we gonna do me and my freind is log the curve in x-y mode the compare to another cvslike first log to second log or something like thisadd another menu to the ppmscope and parse the cvs log by name not date or maybe separate each log from anotherby the name realy nice code im asking pemission from you to mess around with the code a bit so i see what i can dohere is a screeen shoot of the code im hammering my mind now a littelAttachments areaPreview attachment Nouveau Image bitmap.JPGJonathan Weaver <jonw0224@aim.com>Feb 18to meYassine,Feel free to modify the code to suit your needs.Thanks,Jonathan--Jonathan WeaverKM4FIKhttp://jonw0224.weebly.com/and here is the fados 9f1 webpageprotarge.com/?p=products&id=29
