cdma2000 Reverse Link Modulation for Component Test
This section teaches you how to build reverse link cdma2000 waveforms for testing component designs. The
waveforms are generated by the signal generator’s internal dual arbitrary waveform generator.
Activating a Predefined cdma2000 Reverse Link State
This procedure teaches you how to perform the following tasks:
• “Selecting a Predefined cdma2000 Reverse Link Setup” on page 312
• “Generating the Waveform” on page 312
• “Configuring the RF Output” on page 312
Selecting a Predefined cdma2000 Reverse Link Setup
1. Press
Preset.
2. Press
Mode > CDMA > Arb CDMA2000.
3. Press
Link Forward Reverse until Reverse is highlighted.
4. Press
CDMA2000 Select > Pilot.
This selects a pilot cdma2000 reverse link waveform. The display changes to FWD CDMA2000 Setup:
SR1 Pilot.
Generating the Waveform
Press
CDMA Off On until On is highlighted.
This generates the predefined pilot cdma2000 reverse link waveform. During waveform generation, the
CDMA and I/Q annunciators appear and the waveform is stored in volatile Arb memory. The waveform is
now modulating the RF carrier.
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 predefined cdma2000 reverse signal is now available at the RF OUTPUT connector of the signal
generator.
