Generate the Signal at the RF Output
Perform the following steps on both ESGs to generate a signal at the RF outputs.
1. Press
W-CDMA Off On. On is now highlighted and the WCDMA and I/Q annunciators are
displayed.
2. Press
I/Q > I/Q Source > Ext I/Q. This sets the I/Q source to external.
3. Press
RF On/Off. The RF ON annunciator is now displayed.

Configure the E4406A Option BAF VSA Series Transmitter Tester
This section explains how to set up the E4406A Option BAF VSA to display the downlink
ESG parameters that were configured in the previous section.
Perform the following steps to show the code domain display:
1. Connect the RF OUTPUT from one of the signal generators to the RF INPUT of the
transmitter tester.
2.
Press Preset.
3. Set the VSA to use an external reference and ensure that it is set to 10 MHz.

6. Set the center frequency to 2.14 GHz and the span to 10 MHz.
Press:
FREQUENCY > Center Freq > 2.14 > GHz
Press: SPAN > 10 > MHz
7. Select code domain measurement.
Press:
MEASURE > More (1 of 2) > Code Domain
8. Adjust the code domain spread code range.
Press:
