W-CDMA Digital Modulation for Component Test
W-CDMA Downlink Modulation
stored in volatile ARB memory. The waveform is now modulating the RF carrier.
For instructions on storing this user-defined multicarrier W-CDMA state to the signal
generator’s non-volatile memory, see “Storing a Multicarrier W-CDMA State” on page 304.
Applying Modifications to an Active Multicarrier Waveform
1. Press
Multicarrier Define.
2. Move the cursor to row 2.
3. Press
Delete Row > Apply Multicarrier.
Notice that the waveform is regenerated to include the modification of the deleted row. Any
changes made to an active multicarrier waveform will not be applied until the
Apply Multicarrier softkey is pressed.
Configuring the RF Output
1. Set the RF output frequency to 2.17 GHz.
2. Set the output amplitude to
−10 dBm.
3. Press
RF On/Off until On is highlighted.
The user-defined multicarrier W-CDMA signal is now available at the signal generator’s
RF OUTPUT connector.
Storing a Multicarrier W-CDMA State
This procedure teaches you how to store a multicarrier W-CDMA state to the signal
generator’s non-volatile memory.
If you have not created a multicarrier W-CDMA state, complete the steps in the previous
section, “Creating a User-Defined Multicarrier W-CDMA State” on page 301.
1. Press
Mode Setup to return to the top-level W-CDMA menu, where W-CDMA Off On is the
first softkey.
2. Press Multicarrier Define > Store Custom Multicarrier > Store To File.
If there is already a file name from the Catalog of MDWCDMA Files occupying the active
entry area, press the following keys:
Editing Keys > Clear Text.
3. Enter a file name (for example, 3CARRIER) using the alpha keys and the numeric keypad.
4. Press
Enter.
