IVI Driver for Agilent 33250 errors out based on unrelated initialization parameters

IVI Driver for Agilent 33250 errors out based on unrelated initialization parameters

‎03-26-2012 12:57 PM

Hi,

 

I am trying to communicate with an Agilent 33250 function generator using the NI HP 33120 IVI C Driver. I have noticed that certain attributes can not be queried depending on how I initialize the IVI driver. See example initailization below:

 

    // The viGetAttribute on HP33120A_ATTR_AM_SOURCE will ERROR in this case
    statusCode = hp33120a_InitWithOptions("USB0::0x0957::0x0407::MY44029973::0::INSTR", VI_FALSE, VI_FALSE,"Simulate=0", &hp33120a);
    // The viGetAttribute on HP33120A_ATTR_AM_SOURCE will PASS in this case
    // statusCode = hp33120a_InitWithOptions("USB0::0x0957::0x0407::MY44029973::0::INSTR", VI_TRUE, VI_FALSE,"Simulate=0", &hp33120a);

 

Is this a bug in the specific driver since the attribute should not be linked to the initialization options for the driver? I have also attached my  entire C code.

 

Thanks!
