The Logging Application
The Logging data acquisition application logs a series of power
measurements for a number of Power Meter channels, plots the results
as a graph, and generates a statistical analysis of the results.

Figure 143 Example Logging Application
The most important parameters for the logging application are:
• [Samples], this is the number of samples that will be performed
during the logging application, and
• [AvgTime], the averaging time is the length of time over which a
signal is averaged. Longer averaging times increase the accuracy
and improve the noise rejection. Longer averaging times also
decrease sensitivity.
The total time for a logging application is the number of samples
multiplied by the averaging time.
The Logging application differs from the "The Stability Application"
on page 237 because all power measurements are performed
consecutively without the possibility of any pause between
measurements, as shown in Figure 143.
All results can be:
• displayed on the screen,
• printed out to hardcopy, or
• saved to disk drive of your Agilent 8164A/B Lightwave
Measurement System.
