CDMA Digital Modulation
IS-95A Modulation
During waveform generation, the CDMA and I/Q annunciators appear and the user-defined
multicarrier CDMA state is stored in volatile memory. The waveform is now modulating the
RF carrier.
For instructions on storing this user-defined multicarrier CDMA state to non-volatile memory,
see “Storing a Component Test Waveform to Memory” on page 218.
Configuring the RF Output
1. Set the RF output frequency to 890.01 MHz.
2. Set the output amplitude to
−10 dBm.
3. Press
RF On/Off.
The user-defined multicarrier CDMA signal is now available at the RF OUTPUT connector.
Applying Changes to an Active Multicarrier CDMA State
If the CDMA format is currently in use (CDMA Off On set to On) while changes are made in the
Multicarrier CDMA Setup table editor, you must apply the changes before the updated
waveform will be generated.
From the Multicarrier CDMA Setup table editor, press the following keys to apply the
changes and generate a new user-defined multicarrier CDMA waveform based on the updated
values:
Return > Apply Multicarrier.
To store a custom multicarrier CDMA state file, refer to, “Storing a Component Test
Waveform to Memory” on page 218.
To recall a custom multicarrier CDMA state file, refer to “Recalling a Component Test
Waveform” on page 219.
