Getac

APMA can export the data to Microsoft Excel format files for further use. For Getac new launch and under development
product, Designers are using this APMA system to diagnose the power plane design in each stage (EVT/DVT/PVT).
Power saving technology can effectively help reduce the system heat, where a cool system will help reduce the problem
caused by thermal issue with more power saved to deal with the thermal. It is indeed, a positive loop and a significant
progress for us. Getac will keep developing advanced power saving technology in the future.
Enabling outdoor applications, particularly essential to mission critical use in outdoor environment
without power.
Strong engineering design, test & manufacturing capabilities that help customers differentiate themselves
from their rivals in the vertical marketplace.

How do we achieve a demand-based power supply? A demand-based power supply system shall only provide adequate
energy to the mother board. An over -designed DC/DC will increase the bill of material (BOM) cost while insufficient DC/DC
design will reduce efficiency and cause energy to convert to heat, and lead to more energy consumed for cooling purpose
eventually. A fully-satisfactory power design not only helps save costs but also increase the power module design efficiency
to lead to more power saving.
Designing an adequate DC/DC power supply module is always a challenge to engineers. It is because some sub-portions of
DC/DC that generated by other high voltage DC/DC will make it difficult to identify the instant power requirement of all
sub-DC/DC at the same time, particularly the CPU core voltage, which changes frequently Designing an adequate DC/DC
power supply module is always a challenge to
engineers. It is because some sub-portions of DC/DC
that generated by other high voltage DC/DC will make
it difficult to identify the instant power requirement of
all sub-DC/DC at the same time, particularly the CPU
core voltage, which changes frequently because of the
CPU power saving technologies, e.g. the SpeedStep®
technology of Intel and PowerNow!TM technology of
AMD. It is also hard to clarify the relation between each
DC/DC module as not all peak current of each DC/DC
will happen at the same time. In other words, the real
power budget can’t be obtained through DC/DC
measurement one by one. The measurement shall take
place simultaneously and be accumulated for a long
time until the system is balanced to get correct data.
The Auto Power Measure and Analyze utility (APMA)
will automatically calculate the data latched from the
data acquisition equipment and output useful informa-
tion such as maximum current, maximum power,
average current, average power etc...And also, the
