To Demodulate And Analyze An Edge Signal - Agilent Technologies 89410A Operator's Manual

Using Digital Demodulation (Opt. AYA)

To demodulate and analyze an EDGE signal

This task shows you how to demodulate an EDGE (Enhanced Data rates
for GSM Evolution) signal. The EDGE signal used in this task was
generated with the HP/Agilent E4433 ESG Series Signal Generator, with a
frequency of 5 MHz, amplitude of 0 dBm, and a framed (pulsed) data
format. Option B7A must be installed to demodulate EDGE signals.
