Scans and displays the power of all 32 SYNC-DL codes in sequential order, including Ec/Io (dB) and Tau (µs). DwPTS Power and Pilot Dominance values are displayed below the table of codes (Figure: “TD-SCDMA/HSDPA OTA Code Scan”). The Scrambling Codes (SC) corresponding to each SYNC-DL code are also displayed next to each code (for easy reference).
Displays the code power versus Tau in a bar graph format. The horizontal axis (Tau) has dynamic scale. The six strongest SYNC-DL codes are displayed below the bar graph with their Tau (us) and Ec/Io (dB) values. DwPTS Power and Pilot Dominance values are displayed below the table of the six strongest codes (Figure: “TD-SCDMA/HSDPA OTA Tau Scan”).
Pilot dominance is a measure of the strength of the strongest code compared to the next strongest code in the same channel.
