W-CDMA Downlink Digital Modulation for Receiver Test

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 14-1).
