The Stability Application
The Stability 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 155 Example Stability Application
The Stability application differs from the “The Logging Application” on
page 242 because you set the averaging time, the total time, and the
maximum number of measurements and all power measurements and the
instrument calculates a period time, a new measurement is started after
the completion of every period time. Period time may be greater than or
equal to the averaging time you set and is always greater than or equal to
100 ms.
This leaves the following two possibilities:
• The averaging time is less than the period time, there is a dwell time between
the commencement of each power measurement, as shown in Figure 155 .
This can happen because:
• the maximum number of power measurements multiplied by the averaging
time is less than the total time or
• the averaging time is less than 100 ms.
• The averaging time is equal to the period time, all power measuremant are
performed without any dwell time.
