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 159 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 274 because all power measurements are performed consecutively
without the possibility of any pause between measurements, as shown in
Figure 159 on page -261.
All results can be:
• displayed on the screen,
• printed out to hardcopy.
