3GPP Recommended Dynamic Range and Interference Tests

Application Examples

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

W-CDMA wanted signal generator

MG3681A Digital Modulation Signal Generator
MU368040A CDMA Modulation Unit
MX368041B W-CDMA Software

MG3681A Digital Modulation Signal Generator 
MU368040A CDMA Modulation Unit
MX368041B W-CDMA Software
MU368060A AWGN Unit

Combiner 
(MA1612A, etc.)

Interfering signal 
(W-CDMA modulation) 

Wanted signal
(W-CDMA modulation)

Wanted signal
(W-CDMA modulation)

AWGN

Interfering signal 
(CW)

DUT

(receiver, etc.)

Interfering signal and AWGN generator

Signal generator for wanted signal and AWGN

MG3681A Digital Modulation Signal Generator
MU368040A CDMA Modulation Unit
MX368041B W-CDMA Software  
MU368060A AWGN Unit 

AWGN

 Wanted signal
 (W-CDMA modulation)

DUT

(receiver, etc.)

  

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.
