Tektronix has added a High Speed Downlink Packet Access (HSDPA) software option to its NetTek Wireless RF Field Tester, enabling network providers to more easily diagnose HSDPA NodeB transmitter problems and effectively manage their 3G networks. NetTek HSDPA capabilities include demodulation measurements such as code domain power, pilot and sync power, scrambling code and EVM. The modulation detection functionality allows identification of the modulation type in use (QPSK or 16QAM); on-screen notification is provided when 16QAM is detected and the corresponding channels are represented in a color coded format.
