RF Record and Playback
ثبت نشده
چکیده
Designed for use in capturing real world RF signals and then replaying them back in the development lab when developing RF products. Using custom front end along with standard NI RF PXI based hardware, the system can record signals up to 2.7 GHz. The software includes a ready to run LabVIEW based application and a high level toolkit that can be modified using LabVIEW to control all functions of the system.
