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 interfering signal source (W-CDMA modulating, CW) and an AWGN source. Furthermore, since mixed Uplink W-CDMA signal and AWGN internally can be outputted by setting the C/N in MX368041B, the base station receiver dynamic range test is realizable by one MG3681A. When both the MU368030A Universal Modulation Unit that installed MX368033A CDMA2000 1xEV-DO Signal Generation Software or MX368031A Device Test Signal Generation Software is mounted, one MG3681A can be utilized as a wanted signal source (CDMA2000 modulating), an interfering signal source (CDMA2000 modulating, CW) and an AWGN source. Furthermore, when both MU368040A CDMA Modulation unit are also mounted, since mixed CDMA2000 signal and AWGN internally can be outputted by setting the C/N in MX368033A or MX368031A, the base station receiver dynamic range test is realizable by one MG3681A. • Configuration of Communication System Software and Expansion Unit Expansion units Communication system Applicable software Expansion unit W-CDMA (3GPP) CDMA2000 —— MU368060A AWGN Unit The expansion unit is installed in the MG3681A Digital Modulation Signal Generator mainframe. 2 Application Examples • 3GPP Recommended Dynamic Range and Interference Tests This test does not require a separate signal generator for both interfering signal and AWGN.
