4. Press Enter.
The user-defined multicarrier W-CDMA state is now stored in non-volatile memory and the file name is
listed in the Catalog of MDWCDMA Files. Note that the actual waveform is not stored; the parameters
for generating the signal are stored. The RF output amplitude, frequency, and operating state settings are not
stored as part of a user-defined W-CDMA state file.
Recalling a Multicarrier W-CDMA State
This procedure teaches you how to recall a multicarrier W-CDMA state from the signal generator’s
non-volatile memory.
If you have not created and stored a multicarrier W-CDMA state, complete the steps in the previous
sections, “Creating a User-Defined Multicarrier W-CDMA State” on page 419 and “Storing a Multicarrier
W-CDMA State” on page 422.
1. Press
Preset to clear the stored W-CDMA waveform from volatile ARB memory.
2. Press
Mode > W-CDMA > Arb W-CDMA.
3. Press
Multicarrier Off On.
4. Press
W-CDMA Select > Custom W-CDMA Multicarrier.
5. Highlight the desired file (for example, 3CARRIER).
6. Press
Select File.
7. Press
W-CDMA Off On until On is highlighted.
The firmware generates the selected multicarrier W-CDMA waveform in volatile ARB memory. The
waveform is now modulating the RF carrier.
