4. Functionality
The PXI-7625 operates as a dual 4×1 multiplexer, enabling the user to connect one of four input channels to a common output per multiplexer section. Each multiplexer can be controlled independently, allowing simultaneous routing of two separate signal paths.
How It Works:
- Each 4×1 MUX section contains four input ports and one output port.
- Through software or hardware control via the PXI backplane, the user selects which input channel is connected to the output.
- The switching mechanism ensures low insertion loss and high isolation, maintaining signal integrity across the full 3 GHz bandwidth.
- The dual configuration allows parallel operation, supporting multi-signal testing or dual-device measurement setups.
Use Cases and Applications:
- RF and microwave signal routing in automated test systems
- High-speed analog and digital signal switching
