Aeroflex announced it has added an additive white gaussian noise (AWGN) source to its IQCreator Windows-based software application. The application lets users set up a wireless carrier modulation scheme and then create an arbitrary waveform file for use with the IFR 3410 and 3020 PXI radio frequency signal generators. The AWGN source transforms an RF signal generator into a noise generator and lets users generate flexible and precise standalone AWGN power and repeatable signal-to-noise ratios, the company said.
