IviSwtch Extension Capability Groups
The IviSwtch class driver identifies VIs and properties that belong to an extension group with the following abbreviations. Instrument specific drivers are not required to implement any of the extension capability groups. If you use VIs and properties that belong to extension capability groups, every instrument specific driver that you use must implement those extensions.
| Group Name | Description |
| IviSwtchScanner | Defines extensions for instruments capable of scanning channels. |
| IviSwtchSoftwareTrigger | Defines instruments capable of receiving software triggers and implements the IviSwtchScanner extension group. |
IviSwtchScanner defines extended capabilities for switches that can wait for the trigger to establish or break paths on the switch module, and assert a trigger upon completed task. The switches that can perform such tasks are the part of the IviSwtchScanner extension group.
IviSwtchSoftwareTrigger defines extended capabilities for switches that can support IviSwtchScanner extension group and receive software triggers. The following figure illustrates a series of I/O channels connected through the switch module internals.
