National Instruments Chassis and Vector Signal Transceivers

Access

System is named Instrument1, running embedded windows. Access via remote desktop. Currently using the secure login credentials.

Roles

Replacing the old instrument1 machine. Acting as host for interference service, and using two onboard VSTs for noise injection, arbitrary signal injection, and spectrum monitoring, in order of importance.

Also acting as host for communication with spectrum analyzer, and other GPIB instruments.

Will eventually host similar capabilities for LTE and WLAN signal generation and analysis.

Ultimately, we want to provide labview access to end users, but we need to ensure a return to consistent state first.

Software

Code is written in C#, LabVIEW is available but not currently in use.

NI provides .net wrappers for their DLLs.

• NI-RFSG (signal generation)
• NI-RFSA (signal analysis)
• NI-RFmx
• LTE Toolkit - Generation
• LTE Toolkit - Analysis
• WLAN Toolkit - Generation
• WLAN Toolkit - Analysis
