National Instruments PXI-2543 PXI RF Multiplexer Switch Module

The PXI-2543 Switching Multiplexer Module (Part Number: 778572-43) has a NI-SWITCH instrument controller, which incorporates support files for Microsoft Visual C ++ and Microsoft Visual Basic. Each channel connects with the corresponding common by shutting its relay (the relay name depends on the relating signal name). For instance, the relay interfacing CH9 to COM9 is CH9. The user can have various channels associated with the corresponding commons.

The switch control circuitry (SCC) incorporated in this model is in charge of opening and shutting relays on the NI PXI-2543. The user can load summons for the SCC into memory storage by utilizing the driver software received with the unit. There are two purposes for storing the summons in memory before the SCC can process them:

1) The operate and release times for the NI PXI-2543 are 10 ms and 5 ms, individually. Utilizing memory storage, the product can send numerous orders to the SCC without waiting for a relay activity to complete.

2) The memory is utilized to store a scan list essential for hardware random scanning.

The user can also utilize the driver software to arrange the switch card for constant or one-time scanning. In continuous scanning, the switch card cycles through the scan list until the user disables scanning. For one-time scanning, the switch card goes through the scan list a single time.
