■ AWGN (Additive White Gaussian Noise) Supports Dynamic Range Test

When performing the receiver dynamic range test specified by 3GPP, AWGN with a W-CDMA modulation signal is required.

Either of the AWGN waveform patterns AWGN_3_84MHz_x2 or AWGN_3_84MHz_x1_5, which are stored on the MG3700A internal

hard disk, can be used for an AWGN signal.

Since a single MG3700A can add a W-CDMA uplink modulation signal and AWGN signal internally and output them as a combined

signal, it is useful for a simple dynamic range test for base station receivers.
