MATLAB: Problem with connecting an oscilloscope to MATLAB

Question

Hi, I am trying to connect a Tektronix MDO3024 oscilloscope to MATLAB. I am working on windows 10 and MATLAB R2016a. I am simply trying to get the waveform.

I installed TekVISA 4.04 and run tmtool to check if the oscilloscope is connected properly. Everything was ok.

This is the program I have tried:

myScope = oscilloscope();
myScope.Resource = 'USB0::0x0699::0x0408::C026901::0';
connect(myScope);
enableChannel(myScope, { 'CH1'  ,  'CH2'});
w = getWaveform(myScope);

When the program try to run getWaveform I get an error “Instrument returns error during execution”. I tried to instal NI-VISA 17.0 then NI-VISA 5.4 nothing changed.

If anyone can help me to solve the problem it will be great.

Answer 1

I used

myScope.WaveformLength = 1000;

and the problem is solved.
