  • 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 sort by termination.  Additionally, the schematic diagrams on each specification sheet will show termination resistors if the device does include terminations.
