3GPP Signal Analyzer Measurement Guide : W-CDMA/HSDPA Signal Analyzer : Demodulator
 
Demodulator
In the demodulator mode, the RF In is connected to the node B equipment and the unit will demodulate the W-CDMA signal. The W-CDMA/HSDPA demodulator has Code Domain Power (CDP), HSDPA, Codogram and Modulation Summary screens.
Note 
The W-CDMA/HSDPA Demodulator option demodulates both W-CDMA and HSDPA signals. The W-CDMA Demodulator only demodulates W-CDMA signals.
Zoom Function
In CDP and Codogram measurements, the Zoom function can be activated to zoom in on selected OVSF codes. The Zoom function can be set to start from a particular OVSF code.
Note 
Press CDP or Codogram twice to activate the zoom function. The arrow in the lower right corner of the submenu key indicates a sub menu is available.
