W-CDMA Downlink Digital Modulation for Receiver Test
Using W-CDMA Downlink
Using W-CDMA Downlink
This section teaches you how to build real-time W-CDMA downlink modulation for testing mobile receiver
designs. The modulation is generated by the signal generator’s internal baseband generator. The procedures
in this section build on each other and are designed to be used sequentially.
Configuring the Base Station Setup
1. Press Preset.
2. Press
Mode > W-CDMA > Real Time W-CDMA > BS Setup.
This opens a menu where you can adjust the filtering type, chip rate, scrambling code, and
synchronization delay for the simulated base station (see Figure 17-1).

Use the arrow keys or the knob to highlight the data fields to be edited. Once a field has been
highlighted, pressing the
Edit Item softkey enables you to change the value.
