Hi, everyone, I got a problem of using the instrument control toolbox. I want to use the toolbox to control a waveform generator (Agilent 33220a). I have a signal written in m file, sth like:
wave=sin(2*pi*f*t)+cos(2*pi*f*t);
and want to download this wave to the generator. I use the following code to do that:
groupObj = get(deviceObj, 'Arbitrarywaveform');
groupObj = groupObj(1);
invoke(groupObj, 'create', 'volatile',wave);
but every time it seems the wave can't be transmitted to the generator.
Anyone have sugguests on this problem. Thanks in advance.

Can you provide more details:
1) What is the version number of the IVI driver for the 33220A are you using?
2) What version of MATLAB are you using?
3) Are you generating the MDD using the following command:
>> makemid('Agilent33220A.Agilent33220A','Agilent33220A.mdd','ivi-com','IIviFgen')
4) Have you referred to the example here:
