Data Sheet

DPOPWR

DPOPWR Power Measurement and Analysis software transforms
Tektronix digital oscilloscopes into sophisticated analysis tools that quickly
measure and analyze power dissipation in power supply switching devices
and magnetic co

mponents, and then generates detailed test reports
in customizable formats. DPOPWR, used with a Tektronix DPO7000,
MSO70000, or DPO/DSA70000B Series oscilloscope and differential
voltage and current probes, forms a complete measurement system for
power supply design and test. To improve the efficiency of switching power
supplies with increased powe r densities, designers need to analyze power
dissipation a

nd characterize transitions at higher switching frequencies.
Using DPOPWR’s unique switching loss and B-H analysis features, you
can measure switching and magnet ic device power dissipation with a touch
of a button. Tektronix oscilloscopes’ high bandwidth, high sample rate,
and deep memory, combined with the DPOPWR, enable you to efficiently
and accurately characterize switching power supplies by measuring power
loss at the sw

itching device and magnetic component. Reliability at the
component level of the switching power supply can be analyzed using Safe
Operating Area, with mask test capability and measuring the peak flux
density.

With the c urrent harmonic standard (EMC) being imposed worldwide to
maximize the efficiency of the existing total generation capacity, compliance
to the IEC EN61000-3-2, EN61000-3-2 AM14 Standard is critical. Reduce
your development and testing time by using the pre compliance testing
capability o

f DPOPWR to test power supply designs to these standards

from your bench.

DPOPWR enab

les you to set units and scale factor for current and voltage
probes to read the result in the right unit. Automated deskew capabilities
help you to get accurate results.
