tcdemo2.m
This M-file is a demonstration. It shows you how to compare the FRF measurement results of the
digitally filtered, HP3566/67A time-capture data and the orginal filter shapes generated by the
PC-MATLAB Signal Processing Toolbox.
This demonstration requires these files:
• \analyzer\data\matfrf.dat
• \analyzer\utils\sdftoml.exe
The file sdftoml.exe is provided with the SDF utilities; the file matfrf.dat is not. You must create
matfrf.dat on your HP3566/67A. To create matfrf.dat, perform the following steps:
1. Load the matdemo.tim time-capture file into the HP 3566/67A.
2. Run a stable-average measurement.
3. Save the results to \analyzer\data\matfrf.dat (using Save Data).
Note The file matdemo.tim is provided with the SDF utilities. It is a 4 channel,
FRF time-capture file, created with a span of 12,800 Hertz.
