IVI driver Problem. InitWithOptions fails.

[TWGomez]

I am using a TDS5104B DPO and an Agilent 66000 series of DC Power Modules, among many other peices of equipment. I am trying to interface these two via Test Stand 4.0 and NI supplied IVI drivers (V 1.21 for the DPO and V 2.2 for the DC Modules). HOWEVER anything I try from Test Stand results in an an error for these two peices of equipment. The error states that InitWithOptions failed, caused by IdQuery. I verify this in LabView via CIN, I get an error when IdQuery is true, no error when it is false. Is there a way in MAX to set the idQuery to false? Or another method of avoiding this error? I would much rather call this equipment from Test Stand than have to call an Action Statement and use LabView.

Are you sure, that disabling the idQuery solves your problem ?

Usually the idQuery just sends an *IDN? to the device and then compares the returned IDstring of the device with an expected string. If the idQuery fails, either the communication is broken or the used driver doesn't really support the device.

Hi,

Sometimes you have to specify a Model number for the Query to return TRUE.

You can do this either in MAX for the Logical Name under the Driver Options eg "Model:TDS5104B"

or you can do this by setting the Attribute - Driver Setup = "TDS5104B" as part of the IVI step. I think you can do this using the IVI Tool Step.
