Agilent 86038B Photonic Dispersion and Loss Analyzer, Second Edition
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.
