Signal Generation Software
To test mobile handsets for real-world noise conditions, Aeroflex is now including an AWGN (Additive White Gaussian Noise) source with its IQCreator software. The addition of the AWGN feature transforms an RF signal generator into a noise generator. IQCreator is a free Windows-based software application that enables a user to set up a wireless carrier modulation scheme and then create an arbitrary waveform file for use with the Aeroflex IFR 3410 and Aeroflex 3020 PXI series RF signal generators. IQCreator with AWGN allows users to easily and accurately add AWGN to any modulated signal without complex calibration. IQCreator's AWGN feature is appropriate for generating flexible and precise standalone AWGN power and repeatable signal-to-noise ratios (carrier noise or C/N). A precise and repeatable in-channel AWGN is especially important when determining a mobile receiver's sensitivity threshold.
