Hi, I have a problem trying to get the limit test result from the VSA using matlab remote command.

These command worked
app.Display.Traces.SelectedItem.Markers.IsLimitVisible = true;
app.Display.Traces.SelectedItem.Markers.LimitName = "Test01";

but I don't know the command to get to limit test result. Can anyone help?

No one else has this question

Not sure about Matlab command, but the SCPI command to get limit test results for last measurement is:

CALC:CLIM:FAIL?

  Currently I am using matlab to remote control the VSA using .NET API, how can I in the middle of an automated test switch over to SCPI command for that specific command. I need to find the equivalent command in .NET API. Please help.

    I referred to the SCPI command since I don't have the .NET API, so I can't do a search for the equivalent command.
    
    Try opening the API help and search for CLIMIT

      I opened up .NET API help and it has a class called LimitResultData, and in it it has the following public proprerties: Display, Name, Result, X, Y.
      
      I tried the following command
      result = app.LimitTest.SelectedItem.LimitLines.SelectedItem.Result;
      
      However, matlab give me the following error No appropriate method, property, or field 'LimitTest' for class
      'Agilent.SA.Vsa.Application'.
      
      I attached the class diagram for you to view. Hope it helps. Thanks a lot.

        I think this would either be up the tree at the LimitTest level or it could be under Measurement Data (under Trace) or Measurement Class.
        
        It returns the Pass/Fail status of the *current* measurement against the set limits.
        
        BTW, if one or more limit tests are active, it returns the aggregate pass/fail.

        I tried them both as you suggested but no success. I am not sure if Agilent.SA.Vsa.Interfaces.dll included the limit line test result. Do you know if I need to add other dll for this command to work? Currenly in my automated script I included the following dll: Agilent.SA.Vsa.Interfaces.dll, Agilent.SA.Vsa.HardwareExtensions.Core.Interfaces.dll, and Agilent.SA.Vsa.Lte.Interfaces.dll.
        
        Yes, I realized that the limit test return the Pass/Fail status of the current measurement. I used the similar command on the Agilent MXA using SCPI when I need to automate the spectrum analyzer and it worked.

There is no method to retrieve a combined pass/fail status for all limit lines and limit tests configured. These will need to be read individually.
The pass/fail status you will read is for each individual limit line. A limit test can contain multiple limit lines.

For each trace where you have a limit test defined first deterime the number of limit lines using the command.
app.Display.Traces.SelectedItem.Markers.LimitResultCount;

Then read each limit result using the zero based index.
app.Display.Traces.SelectedItem.Markers.LimitResult(index);
