  • PXI RF Multiplexer Switch Module

Issue Details

I have an NI PXI-2547 device and am wondering about the termination characteristics of the device.  Does the device have built in 50 Ω termination on each channel? 

Solution

The PXI-2547 module does not have 50 Ω terminations.  However, other devices, such as the PXI 2545, do have 50 Ω terminations. 

Additional Information

For more information on which modules do have 50 Ω terminations, refer to the RF Multiplexer Switch shop page and check for the description of the module, it will indicate whether if the switch is terminated or not.  Additionally, the schematic diagrams on each specification sheet will show termination resistors if the device does include terminations.
