To Demodulate A Standard-Format Signal - Agilent Technologies 89410A Operator's Manual

Using Digital Demodulation (Opt. AYA)

To demodulate a standard-format signal

This task shows you how to demodulate the NADC signal on the Signals
Disk.
1.
Configure the analyzer for a digital demodulation measurement.
If you haven't already done so, perform the steps in the previous
task, ''To prepare a digital demodulation measurement.''
2.
Digitally demodulate the signal:
Press [
Instrument Mode
[ ], [
Instrument Mode demod type
3.
Choose standard demodulation setup parameters:
Press [
demodulation setup
4.
Modify the standard parameters for this specific signal:
Press [ ], [
Time result length
Press [
]
pulse search off
]
Press
[Auto Scale
If you are demodulating a signal which matches a standard signal type, you
can automatically configure the analyzer for that standard by pressing
[ ] and then choosing the appropriate type. The parameters set
standard setups
when you choose a standard are: demod format, span, symbol rate, meas
filter, ref filter, alpha/BT, result length, pulse search, and points per
symbol. If your signal is not of a standard type you may select individual
parameters in the [
