The Duet Channel Sounder is a two part transmitter and receiver system providing comprehensive analysis including BER Multipath Eb/No and RSSI. The Duet is a sequential correlating channel sounder. The Duet Channel Sounder provides insight into propagation analysis in the presence of fades noise and multipaths for the PCS band assisting engineers in the planning and deployment of PCS Systems. 1930 MHz to 1990 MHz in 50 kHz steps (standard)
