2. Press W-CDMA Define > Store Custom W-CDMA State > Store To File.
If there is already a file name occupying the active entry area, press the following keys:
Editing Keys > Clear Text.
3. Enter a file name using the alpha softkeys and the numeric keypad.
4. Press
Enter.
The user-defined W-CDMA downlink/uplink state is now stored in non-volatile memory and
the file name is listed in the catalog of 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 W-CDMA Downlink/Uplink State
This procedure teaches you how to recall a W-CDMA state from the signal generator’s
non-volatile memory.
If you have not created and stored a W-CDMA state, complete the steps in the previous
sections, “Creating a User-Defined W-CDMA Downlink State” on page 295 and “Storing a
W-CDMA Downlink/Uplink State” on page 299, then preset the signal generator to clear the
stored CDMA waveform from volatile ARB memory.
1. Press
Mode > W-CDMA > Arb W-CDMA.
2. Press
W-CDMA Select > Custom W-CDMA State.
3. Highlight the desired file.
4. Press
Select File.
5. Press
W-CDMA Off On until On is highlighted.
The firmware generates the user-defined W-CDMA waveform in volatile ARB memory. The
waveform is now modulating the RF carrier.
For instruction on configuring the RF output, see “Configuring the RF Output” on page 299.
