Instrument Configurations
The following table lists the hardware connectors that correspond to the valid port strings used by the driver software to specify the ports available for you to select and configure based on the hardware configuration you purchased.
| Port String | Hardware Module | Hardware Connector |
|---|---|---|
| if0 | PXIe-3621 | IF IN/OUT 0 |
| if1 | IF IN/OUT 1 |
For example, if you specify if0, you are specifying the IF IN/OUT 0 connector on the PXIe-3621 front panel to transmit or receive an IF signal.
Note While both IF IN/OUT 0 and IF IN/OUT 1 ports are configurable as the generator output or analyzer input, NI recommends you use IF IN/OUT 0 as the generator output using the OUT port and IF IN/OUT 1 as the analyzer input as the IN port.

- Selecting Available Ports
You can use the NI-RFSA and NI-RFSG APIs to query available ports on your VST and specify which ports to use. This functionality is important for VSTs with millimeter wave functionality because these VSTs use different ports depending on the frequency of the signal you are generating or analyzing.
