Product Description

TDSPWR3 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
customizable formats. TDSPWR3, used with a Tektronix TDS5000B,
TDS7000/7000B, CSA7000 Series or TDS6000B models oscilloscope and
differential voltage and current probes, forms a com plete 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 TDSPWR3’s unique
switching lo
magnetic device power dissipation with a touch of a button. Tektronix
oscilloscopes’ high bandwidth, high sample rate and deep memory,
combined with the TDSPWR3, enable you to efficiently and accurately
characterize switching power sup plies by measuring power loss at the
switching device and magnetic component. Reliability at the component
