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.
1. Select two displays and format them:
Press [
Display
], [
2 grids
]
Press [
A
], [
Measurement Data
], [
IQ measured time
].
Press [
Data Format
], [magnitude
log(dB)
].
Press [
D
].
2. Enter a sync bit pattern:
Press [
Time
], [
sync setup
], [
pattern
], [
clear entry
], 000101, [
enter
].
3. Select an offset:
Press [
offset
], 6, [
sym
].
4. Turn on sync search:
Press [
Return
], [
sync search on
]
The search length must be longer than the combination of result length,
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.
The sync word is highlighted when sync search is completed successfully
