National Instruments PXI-2555 PXI RF Multiplexer Switch Module
The National Instruments (Part Number: 778572-55) PXI-2555 is a PXI RF Multiplexer Switch Module. The internal termination of the PXI-2555, which helps prevent high-control reflections that emerge from open channels on the module, makes it perfect for use in video RF applications where such reflections can harm the source. The module includes phenomenal insertion loss, voltage wave ratio (VSWR), and isolation parameters to limit signal degradation. The user can utilize the onboard relay count tracking feature to anticipate relay lifetime and diminish unexpected framework downtime.
The onboard control logic for the NI PXI-2555 Multiplexer Switch Module gives the user access to open and close the relays, with the ability to download up to 1024 irregular scanning instructions. The software included configures the NI PXI-2555 and downloads the scan list to hardware. The scan list itself downloads specifically into the memory of the card to deliver the quickest scan conceivable with no controller intervention. The user can arrange the switch card to process the scan list once or to continuously loop through the scan list.
This model includes an Outside Trigger Input to advance between scan setups in a scan list. By utilizing the driver software, the user can arrange the switch card to course the outer trigger from any of the PXI TTL trigger lines or the PXI star trigger. On the other hand, the user can utilize a software command to trigger the switch card. All outside trigger lines are fine with TTL voltage levels and are edge sensitive. The minimum pulse width from the PXI TTL triggers and PXI star trigger is 70 ns.
