Application Examples

•3GPP Recommended Dynamic Range and Interference Tests

This test does not require a separate signal generator for both interfering signal and AWGN.

•Dynamic Range Test by mixed Uplink W-CDMA signal and AWGN internally

Since AWGN is mixed digitally, the C/N ratio accuracy and stability are excellent.
