The duration of the spike is 0.3 ms. In fact, with the 2 MSa/s sampling rate DAQ,
and the recommendation that the sampling rate employed by the DAQ (or the
test system) should be fi ve times the sampling rate of the signal, the maximum
glitch that can be detected is 2.5 us. In this application, the absolute voltage
is actually not as important since the main purpose of the application is to
monitor the presence of spikes. The DAQ measurements and functionality test
were carried out at the same time, and since it can be determined when a spike
occurs once the data acquisition process has started, it is also possible to easily
and quickly determine the actual status and functionality details of the PMU at
that point in time. Based on this information, the troubleshooting process can be
related to the exact time and situation at which the problem occurred.

Conclusion
With the growing popularity for portable devices, it is necessary to have a quick
and easy design validation of the power management unit. The objective of
monitoring the PMU for stable input and outputs can be achieved using Agilent’s
DAQ. This way it is possible to reduce the time required to resolve the problem.
This is done through a low cost DAQ solution.
