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.
