1. Power Analyzer Option rich@testrack.com

2. History of Power Analysis Software  Strong history of power analysis going back to late 1990’s  Software evolved over time and transitioned to current version in 2003  DA1855A and variety of current probes simplified power probing  12-bit HDO is the right oscilloscope for taking power measurements to the next level

3. Power Analysis Software Option  Measure and analyze operating characteristics of power conversion devices and circuits  Automatic detection and measuring of turn-on, turn-off and conduction losses  Identify areas of power loss with color coded waveform overlay  Streamlined user interface to guide user through various stages of analysis  Operating modes for:  Power switching device measurements  Control loop modulation analysis  Line power harmonics

4. Streamlined User Interface  New power specific user interface walks user through proper setup  Select inputs and configure with Input Settings tab  Choose analysis type, desired test and measurements to be displayed  Shortcuts for statistics and histicons available  All measurements have appropriate power related names for simplicity  Switching Losses, Conduction Loss, Offstate Loss  Choose method of calculating conduction loss depending on probe setup

5. Device Measurement – Power Losses  Areas of power loss are automatically detected, measured and annotated across many cycles  Color coded overlay highlights all areas of power losses on both power and voltage traces  Measurements are automatically calculated and displayed with proper power terminology  No manual gating of switching losses required

6. Device Measurement - Conduction Loss Calculation  User selectable choice of how to display conduction losses  Measure with differential amplifier and probe or calculated based on component specifications  Unique feature enabling simple and accurate conduction loss measurement

7. Device Measurement – Removing Probing Errors  Dedicated interface for proper probe setup and configuration  Controls to adjust Fine DC offset and eliminate skew between channels  Shortcuts to channel menus for probe Autozero and Degauss

8. Device Measurement – Safe Operating Area (SOA)  Easily display SOA for comparison to component specs  Use persistence to monitor SOA during critical events like power supply startup, transient load and transient line changes  Power loss annotator identifies losses on all cycles in long captures  Loss measurements calculated across all cycles with statistics

9. Control Loop - Modulation Analysis  Evaluate loop dynamics of switched mode power device  Plot variation in time of pulse width, duty cycle, period or frequency  Leverages long memory of the HDO to capture control loop performance during startup

10. Line Power – Harmonics Testing  Investigate line power harmonics for pre-compliance to standards like EN61000-3-2  View voltage, frequency and line harmonics simultaneously  Mask testing reports when harmonics are outside the allowed range  Table in the dialog box reports back results and harmonic details  rich@testrack.com
