To Load The Multi-Path Signal From The Signals Disk - Agilent Technologies 89410A Operator's Manual

To load the multi-path signal from the Signals Disk

This task shows you how to load a 16-QAM, multi-path, time-capture signal
from the Signals Disk. Other tasks in this section use this signal to teach
you how to use adaptive equalization.
1.
Initialize the analyzer and select the Digital Demodulation instrument mode:

3.
Load the time-capture data into the capture buffer:
Insert the Signals Disk in the analyzer's disk drive.
Press [ ], [
Save/Recall
Press [ ] (bottom softkey), [
Return
Rotate the knob until the file EQSIGNAL.DAT is highlighted.
Press [ ], [

Using time-captured data causes the analyzer to automatically measure
from the capture-buffer instead of the input channel and sets the center
frequency, span, and resolution bandwidth to those used when the data
was captured. In a typical equalization measurement you would set these
parameters instead of loading captured data.
