CDMA-DSSS Communication System BER Measurement
CDMA-DSSS Communication System BER Measurement
Product Code : 176
Brand Name : Scientech 2131B
Product Description

SCIENTECH TECHNOLOGIES PVT. LTD is established company, engaged as a manufacturer, exporter, importer and suppler of a quality assured product CDMA-DSSS Communication System BER Measurement. The Direct Sequence Spread Spectrum (DS-SS) technique, build in CDMA can accommodate numerous users in one radio channel depending on the voice activity level. With the help of Spread Spectrum the data is spread across available frequency band. On other hand, Bit Error rate(BER) measurement with data data sequence, SNR control, offset control & so on can be performed on Scientech.  Apart from that,  CDMA-DSSS Communication System BER Measurement is widely demanded in the market due to its below features.
