Capture screen image Tektronix 2024B

I run this initially once to create the instrument in the instrument control toolbox:
______________________________________

global tds2024
% Initiate TEKTRONIX_TDS2024B
% It can be written to afterwards
% Needs NI-VISA or TEK-VISA installed on the system to connect via USB

% Create a VISA-USB object.
interfaceObj = instrfind('Type', 'visa-usb', 'RsrcName', 'USB0::0x0699::0x036A::C031507::0::INSTR', 'Tag', '');

% Create the VISA-USB object if it does not exist
% otherwise use the object that was found.
if isempty(interfaceObj)
interfaceObj = visa('NI', 'USB0::0x0699::0x036A::C031507::0::INSTR');
else
fclose(interfaceObj);
interfaceObj = interfaceObj(1);
end

% Create a device object.
global tds2024 % must make this global variable on top level

tds2024 = icdevice('tektronix_tds2024.mdd', interfaceObj);

% Connect device object to hardware.
connect(tds2024);

Then just call the function to get screen image:

get_scope_screen;
