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 components, and then generates detailed test reports
in customizable formats. DPOPWR, used with a Tektronix DPO7000 or
DPO/DSA70000 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 power densities, designers need to analyze power dissipation
and characterize transitions at higher switching frequencies. Using
DPOPWR’s unique switching loss and B-H analysis features, you can
measure switching and magnetic 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 switching 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 current 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 precompliance testing capability of DPOPWR to test power
supply designs to these standards from your bench.
DPOPWR enables
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.
