Example Test Scenarios
Implementing this test involves the use of three applications on the PC controller:
• Agilent Signal Studio (N7600B) for 3GPP W-CDMA. This is a tool for creating W-CDMA
waveform files.
• A proprietary application, made by the manufacturer of the mobile device, which controls the device
through a USB connection.
• Agilent Sequence Studio (U9066A). This is a tool for creating sequences for the EXM test set.
Creating Waveforms
To begin with, we will use Agilent Signal Studio N7600B to create the waveform file which will
modulated the downlink signal to the DUT. Two versions of the waveform file will be created: one which
sets the DUT to a fixed maximum power level, and one which causes the DUT to step through a rising
and falling power sequence.
In Signal Studio, we delete the default Carrier 1, and add a new carrier, selecting “Adv
W-CDMA/HSDPA DL” as the carrier type. (This is the advanced version of the W-CDMA download
waveform; the basic versions do not support the type of waveform coding that is needed for the ILPC
test.)
