The 3GPP and 3GPP2 recommended dynamic range test for W- Expansion units CDMA and CDMA2000 receivers requires AWGN (Additive White Gaussian Noise) to be mixed on the wanted modulated signal. When the MU368060A AWGN Unit is installed in the MG3681A Digital Modulation Signal Generator, AWGN can be generated at real time. When both the MU368040A CDMA Modulation Unit that installed MX368041B W-CDMA Software is mounted, one MG3681A can be utilized as a wanted signal source (W-CDMA modulating), an int
