IVI drivers also increase performance and productivity and decrease development time with the following features:
To download an IVI specific driver,
Note: Refer to the lower right embedded help window in MAX for definitions of all items/fields.
Logical names allow you to define and name multiple driver sessions. You can switch between driver sessions by passing a logical name to the initialize function of a class driver, which identifies the software module and hardware asset to use. For example, you can use MyDmm as a logical name. Application programs written using a class driver use logical names to avoid direct references to software modules and hardware assets.
To create a new logical name, complete the following steps:
To configure the properties of a new logical name or to modify an existing logical name, complete the following steps:
A driver session defines a set of properties for use by IVI instrument drivers such as initial settings for attributes, virtual name mappings, simulation settings, and so on.
To configure the properties of a driver session, complete the following steps:
If the Configurable Settings field is enabled, you can add settings to or remove settings from the Initial Settings list. To add settings, highlight a setting in the Configurable Settings list and click Add. To remove settings, highlight a setting in the Initial Settings list and click Remove.
Note: If the driver does not define configurable initial settings, the list will be empty.
In both cases, you can modify the value of the initial setting.
To swap an instrument, select the appropriate logical name item under Logical Names in the configuration tree. On the configuration panel, select the different driver session that your logical name should refer to from Driver Sessions.
IVI opens many possibilities for instrument driver users. Logical names and virtual instruments make IVI drivers interchangeable and intelligent. MAX helps you to easily and conveniently configure logical names and virtual instruments while maximizing the capabilities of IVI drivers.
