Would it be possible to just hardcode a few lines in the SetChannelConfig in DRS.cpp method as such:
fChannelConfig = 0x01; //gives me eight
d = fChannelConfig | (fDominoMode << 8) | (1 << 9) | (fWSRLoop << 10) | (0xF8 << 8);
Write(T_CTRL, REG_CHANNEL_CONFIG, &d, 2);
fChannelDepth = 8 * (fDecimation ? kNumberOfBins/2 : kNumberOfBins);// gives eight times the bins
then modify the GetWave method/function to include another else if statement similar to "else if (fChannelCascading == 2) {" but would be modifidied for fChannelCascading == 8?
By, "But then you will hit the hard-wired limit in Osci.cpp" do you mean hard-coded? Would changing the hard code just amount to resizing all of the arrays, and replacing all the '2*kNumberBins" with '8*kNumberBins' ?
I'm afraid of drs_exam.cpp because it doesn't come with all the perks of Osci.cpp. It seems less daunting to just modify Osci.cpp then to try understanding everything I need to include in drs_exam.cpp because I'm also using an external trigger, and saving the waveform to an external text file.
Thanks!

Sure it would be possible to code it, but it's not just a few lines. Besides Osci.cpp you have to massage DOScreen.cpp, Measurement.cpp and probably more since they all rely on the array size of the waveform. So if I would do it it would take me probably a couple of days including the debugging, which I don't have right now. Furthermore, as I said you have to combine all eight channels properly. For two channels, it's already pretty complicated (see lines 3537+ in DRS.cpp). I had to make myself a visual scheme in order to understand it correctly, which I attached. For eight channels, the write shift register (WSR) can have values 0-7, depending in which channel you got a trigger. Then you have to sort it out again to get one linear array with the proper order of the fragments. So you see, it's not just changing a few lines of code. In principle it's possible, but it's lots of work.
Best regards,

Stefan, thanks for your help so far. If I go with your plan A of just modifying drs_exam.cpp, is there a quick way to get it to save the data from the wave, like how osci.cpp spits out an xml file? (Ignoring the cascading aspect for now)
Thanks again :)

Well, you have to learn C programming, I won't do it for you. drs_exam.cpp contains already code to write to the ASCII file data.txt, so you just can use that or modify it to your needs.

Ha! So then the answer is no, there isn't a ready made function/method to pull out the timing and voltage, like how it was done in osci.cpp. That's all I wanted to know. (Not whether you would write it for me! Only trying to save time!) Thanks!
