W-CDMA Uplink Modulation
Applying Channel Modifications to an Active Waveform
To apply channel modifications to an active waveform (
W-CDMA Off On set to On), you must first press the
Apply Channel Setup softkey before the updated waveform is generated. For example, perform the following
steps:
1. Press
W-CDMA Define > Edit Channel Setup.
2. Move the cursor to row 2.
3. Press
Delete Row > Return > Apply Channel Setup.
Notice that the waveform is regenerated to include the modification of the deleted row. Any changes made in
the Edit Channel Setup table editor while a waveform is active will not be applied until the
Apply Channel
Setup
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 custom W-CDMA uplink signal is now available at the signal generator’s RF OUTPUT connector.
To store a W-CDMA uplink state, refer to “Storing a W-CDMA Downlink/Uplink State” on page 417.
To recall a W-CDMA uplink state, refer to “Recalling a W-CDMA Downlink/Uplink State” on page 418.
