Automation Using Matlab

Dear all, I would like to use the DEWE-5000 oscilloscope for automatic testing. That means that the oscilloscope shall be fully remote controlled by MATLAB running on another computer. Until now, I was able to estlablish a connection to DEWETRON using following MATLAB sequence: ACTX = actxserver('Dewesoft.App', 'machine', '10.0.1.79'); ACTX.Init; ACTX.Enabled = 1; ACTX.Visible = 1; ACTX.Top = 100; ACTX.Left = 100; ACTX.Width = 1024; ACTX.Height = 768; ACTX.SetInstrument(1); ACTX.ShowStyle = 2; Performing this sequence, I succeeded in starting up DEWEsoft at DEWE-5000; a sequence to quit I found as well. Now I am trying to perform very basic actions like scaling time- and y-axis, setting an auto-trigger etc. using the ACTX handler in MATLAB. Unfortunately, I did not find any working command in order to do this. Especially I am irritated that the command ACTX.SetScopeParams(0, 0, IChannel, 0) - where IChannel = ACTX.Data.Used.Item(0); and AI0 has a sin at the input - as documented in the DCOM reference on pgs. 62 and 121 gives the error "??? No method 'SetScopeParams' with matching signature found for class 'COM.Dewesoft_App'." I now wonder: Is it actually possible to fully remote control the DEWE-5000 via MATLAB? And if yes: Where can I find a more detailed manual on the commands and their way of use? I would be very grateful for any constructive answer. Best regards, Axel

Dear Axel, I have crated a demo file for you how this should work. Also I have a few questions and I can see a mistake in your code. Can you please contact us on the support mail ([email protected]), so we can send you test files and help you with the other issues. Best regards, Tilen.
