3 Enter the number of sweeps you would like to occur. If you want a lot of sweeps
as fast as the instrument can acquire, enter the number of measurements you
want in the measurements block and leave everything else at the default. If you
want the program to pause between measurements, enter the length of time to
pause. You can enter fractional minutes. Sometimes for statistical purposes, you
may want a burst of measurements repeated at some interval. For example, you
may want 16 measurements taken every hour for 12 hours.
4 Make sure to tell the program which port to pull data from. The measurements
will be run as you configure from the front panel, and the program will pull the
data from the port you specify (whether or not new data has been gathered for
that port.)
5 Enter the directory you would like the data to be stored to on the local computer.
You will get one file for every measurement with Wavelength, Gain, Group Delay
and Chromatic Dispersion. The file name is noted at the bottom of the Collection
frame. You will also get a single ODA_stats file with the statistics for the Gain
and Group Delay. The program will use as short a file name as it can. For data
files, it uses ODA_<date>_g001_m001.csv, where g is followed by the group
number, m is followed by the measurement number. If the name is already in
use, the program will insert the date to make the name unique, and avoid
overwriting data. The <date> used is the time the first sweep is completed. The
same <date> string is used for the entire run, so all the files have the same
signature. The format of putting the date before the group and measurement
indexes forces a standard ASCII directory sorting to group all the data from a
single run together in the correct order. Make sure the directory you specify
exists before you start the run.
the files are easier to deal with if you put each run into a separate

directory.
6 Click Start and observe the measurement results as they are taken.
The statistics are calculated for Gain and Group Delay. The All
Measurements block is calculated treating all wavelengths of all
measurements equally. This is useful for measuring very flat and stable
