To view a W-CDMA signal
All tasks in this chapter were created using a 3GPP 1999 forward-link
signal (option 080). The signal was generated with an HP/Agilent E4433
ESG Signal Generator at 5 MHz, –10 dBm, and using the channel
definitions shown below. If you are using a different W-CDMA signal
(i.e., trial 1998 forward-link signal (option B73) or ARIB 1.0-1.2 forward-link
signal (option B79)), the tasks in this chapter still apply . However, in the
next task (To demodulate a W-CDMA signal), make sure you set the
demodulation parameters to match your signal.
Note Older E4433 ESG Signal Generator’s may flip the frequency spectrum at 5 MHz.
If necessary, correct for this when you demodulate the signal in the next task
(To demodulate a W-CDMA signal) by pressing [
Instrument Mode], [demodulation setup],
[
freq spectrum mirror].

DPCH 480 6 – 4.45
The following steps show you how to view your W-CDMA signal in the
Vector instrument mode to verify that the signal is present and that the
analyzer’s center frequency, span, and input range are set correctly.
