To Set Up Sync Search - Agilent Technologies 89410A Operator's Manual

Using Digital Demodulation (Opt. AYA)

To set up sync search

In this task you learn how to synchronize your measurement by using a
specific bit pattern within the chain of bits. You learn how to define sync
words and set an offset. Since sync search is often used with pulsed
signals, this example assumes you have already acquired and demodulated
a pulsed signal as shown in the previous task.

sync pattern, and offset. The sync pattern may include up to 32 symbols.
The offset may be positive or negative. See the online help topics for
more information on these keys.
