The function generator screen paramaters are all reset to their default values. If interchangeability is not necessary for a particular client application, it is often simpler to instantiate the IVI-COM driver directly. If the Interchange Check attribute is enabled, the specific driver maintains a record of each interchangeability warning that it encounters. You changed your response to Helpful.

The IVI-defined Initialize function offers a variety of options and parameters that control fundamental aspects of the driver’s behavior.
Output trace log of all driver calls to an XML file in the same directory as the application executable accessing the driver. Validating attribute initiailzing and function parameters is useful for debugging.
Specifies additional settings supported by the driver, but not defined by IVI. If the Interchange Check attribute is enabled, the specific driver maintains a record of each interchangeability warning that it encounters.
I also see this problem when trying to communicate with an Agilent oscilloscope. Returns an instrument handle initlalizing you use to identify the instrument in all subsequent instrument driver VI calls. Download Help Windows Only.
ClassPrefix Initialize With Options
Opens a session to the specified device using the interface and address you specify for the Resource Name parameter. The function generator screen paramaters thhe all reset to their default values.
Avoid creating multiple concurrent instrument handles to the same physical instrument. The user calls the Get Initializint Coercion Record function to extract and delete the oldest coercion record from the list. This VI performs the following initialization actions: All of the iniyializing resulted in the timeout error. Specifies how often the driver should save trace data to the trace log file.
In any event, the client application will have a direct reference to the specific driver, so the program would not be interchangeable.
If you want to use your program with a different physical instrument, you change the configuration of the logical name to use the driver session for the new physical instrument. The default value is 1.
Circumstances can arise where it is undesirable to send an ID Query command string to the instrument. Although you can create more initiqlizing one instrument driver handle for the same resource, it is best not to do so.
The same error occurs when I: If so, how iv I change the timing? A good troubleshooting step to try would be go into the VI containing the VISA read and write functions, turn on highlight execution and see where the timeout occurs, increase the timeout and try again.
Message 5 of Numeric value in elements. For MAX options, I’ve tried: Specifies whether the IVI specific driver queries the instrument status at the end of each user operation. If the IVI Configuration Store is not used a resource descriptor is passed as the ResourceName instead of a logical name then any setting that is not specified has a default value as specified by IVI. Numeric value in bytes TraceArraySizeMax Specifies the maximum number of elements to trace for array parameters.
Initializing the IVI-COM Driver
Specifies the maximum number of elements to trace for array parameters. Although you can create more than one instrument driver handle for the same resource, it is best not to do so. Is it really a timeout issue? The driver session, in turn, identifies a specific driver and device and specifies the initializinv settings for the session. Message 3 of The session handle is not valid.
