TDSPWR2’s Ideal Partners
TDS5000 & TDS7000 Oscilloscopes
Digital Phosphor Technology Fast waveform capture
rate Live color analog-like
display
Long record length Advanced math Up to 1GHz bandwidth
and 5GS/s sample rate
Measurement Challenge
Switching Loss
Most switching loss occurs during transitions Minimize transition time to
reduce switching loss
Must be able to measure turn-on, turn-off and cycle power loss
Most oscilloscope solutions don’t measure to this level of detail
TDSPWR2 Solution
Switching Loss
TDSPWR2 automatically computes the switching loss at Turn-on, Turn-off and for the entire cycle at the switching device
Min, Max and average values computed for trend data on switching loss over time in a dynamic load situation
HiPower Finder feature analyzes pinpoints areas of instantaneous power dissipation
Measurement Challenge
Core Loss & B-H Analysis
Magnetic components designed to enhance performance may cause power dissipation
Important to know the operating limits of these components in order to determine safe operation of the power supply
No current oscilloscope solution can provide this data
TDSPWR2 Solution
Core Loss & B-H Analysis
TDSPWR2 provides visualization of the inductor behavior
Automatically measures core loss and the inductance value of the coil
TDSPWR2 automatically displays B-H plot for further analysis
Measurement Challenge
Test Report Generation
Customers demand lengthy, custom-formatted test reports
Manual report preparation is very tedious and time-consuming
TDSPWR2 Solution
Test Report Generation
TDSPWR2 enables automatic generation of customized test reports
Automatically generate reports with a push of a button
Create templates, with custom oscilloscope fields, settings and measurements
Size selection Editable Easily exportable file format
Measurement Challenge
Analysis of Safe Operating Areas
Designers must analyze and monitor the safe operating limits in a real-world environment with fluctuating power demands
Requires capture and analysis of long-duration events
TDSPWR2 Solution
Analysis of Safe Operating Areas
TDSPWR2 and a DPO provide the long record length and automatic measurements to make this task fast, easy
Long record length of scope captures entire event
Automatically measure and determine safe operating area Locate and analyze the
linkage between safe operating area and the waveform in the time domain
Measurement Challenge
