Tektronix TDSPWR2 Reference manual
Getting Started with TDSPWR2
Y ou can use this side of the Quick Reference to start to take
measurements with the Power Measurement and Analysis
Software (TDSPWR2). The other side contains a complete
menu tree for TDSPWR2 software.
NOTE. For complete operating instructions
and General Safety information, refer to the
Online Help for the application.
The TDSPWR2 Power Measurements and Analysis
software transforms a digital oscilloscope into an analysis
tool that measures and analyzes power dissipation in power
supply switching devices and magnetic components. It then
generates detailed test reports in customizable formats.
Performing a Switching Loss Measurement
To measure Switching Loss, follow these steps:
1. Select File> Run Application> TDSPWR2 in the
oscilloscope menu bar.
2. Connect the probes to the device under test. For
example, the test setup for Switching Loss is shown
below.
4. Select the Switching Loss option.
5. Configure the options in the common configuration
panel.
6. Select the Source and assign the Voltage and Current
channels.
7. Set the appropriate I-Probe settings.
9. Push the “Running Man” button to start taking
measurements. If the measurement is successful, the
application automatically displays the results. You can
also view the results by selecting View> Results from
the application menu bar.
10. The application displays results for the measurement in
three tabs: T-on Power Loss, T-off Power Loss and
Power Loss.
3. In the Power Device tab, select Power Dissipation. Press
Configure.
