Hi RogueSS,
first of all welcome to the forum.
Came across this forum topic when I realized the FFT on this scope was rather lacking.
You are correct that the FFT on the original scope is crap. But having said that, it is not implemented in the new firmware. The menu option to enable it is there, but that is it.
So I thought that having access to the .CSV data would allow me to process it on a pc using a python script.
Unfortunately the scope does not give you access to .CSV data.
Correct there is no .csv data available, but there is access to the sample data. In the original firmware it can be found in the .wav files. Someone on this forum made some software to make use of the data. You have to search for it.
In the new firmware there is also the .wav file option, and that provides the full 3000 samples per channel the scope has to offer. I wrote about the format of this file somewhere in this thread
The source can be found in the repository and it is not that hard to find what you need in it. Lost of comments in the code.
So my first question I guess is the following: Is the plan to add this sort functionality(Access to .CSV file via usb) in the future?
I have no plans for it at the moment. Moved on to other projects to learn new stuff.
I will be honest in saying that I have not attempted load this new firmware yet. (Afraid I will brick/damage scope, Significant amount of justification was involved to justify this purchase to my better half )
It is practically impossible to brick these scopes, apart from applying wrong voltages to it of course. Sure it is possible to corrupt the SD card, but that can be swapped easily when you have a screw driver
The procedure described in the repository has been used successfully by several members and is quite simple. All you need is a computer with linux.
Therefore I don't know what functionality have been added so far in terms of MATHS functions.
Will basic maths functions be added: -,+,/,x?
The new firmware basically has the same functionality as the original. Only the FFT is missing. The one extra thing in the new firmware is the ability to select the sample rate apart from the time per division. Read through the previous pages to see a summation of the improvements and problems encountered by other users.
Read the text files in the main folder of the repository that holds the firmware. They give more information about what to do and how things came together. Just follow the link below in my signature.
