viii Advanced Power Analysis
Welcome
Advanced Power Measurement and Analysis software allows power supply
designers to configure multiple measurements with custom defined settings,
measure and analyze power dissipation in switching devices, and measure and
analyze magnetic parameters in a single acquisition. The addition of new
measurements such as Inrush current, Capacitance, and Reactive power provides
more insight into the input / output characterization of power supplies. Designers
who otherwise spend a lot of time manually analyzing power dissipations per
cycle can now, with the Switching loss plot and the Time trend plot, measure
power dissipation at all switching cycles graphically. A single .mht format with
the append feature provides an easy way to generate reports that include
measurements, test results, and plot images. This solution elevates your
productivity to a new level and helps SMPS designers meet pre-compliance
requirements.
Advanced Power Measurement and Analysis software with version > 2.0.0 runs
on DPO/DSA7000C, MSO/DPO5000/B, MSO/DSA/DPO70000C, DPO/
DSA700000D, and MSO/DPO/DSA70000DX series oscilloscopes with
Windows 7 64-bit OS. For WinXP series oscilloscopes DPOPWR solution
version is 1.0.13.
Features and benefits
The software includes the following key features:
■
New measurements such as Inrush current, Capacitance, Reactive power and
Switching loss trajectory plot which provide more insight to Input/output
characterization.
■
Custom source Autoset for vertical and horizontal sets the scope parameters
automatically, increasing your productivity and measurement repeatability.
■
Automatic computation of line frequency provide more accurate results to
Voltage and current Harmonics.
■
Automatic detection of PFC circuit waveforms and prompts the user to use
VG for noisy/ringing switching waveforms.
■
Multiple measurements can be run at same time for single acquisition,
providing correlated power measurements.
■
Synchronization of Time trend plot with actual waveform allow you to
observe the variation of measurements over time.
■
Automatic detection of probes, AutoZero / Degauss, and de-skew utilities.
■
Reference waveform helps you to do post analysis now available for all
measurements.
■
Seamless integration of the application with the oscilloscope allows you to
switch between application and scope easily and debug more effectively.
Advanced Power Analysis ix
Welcome
Key measurements
■
Global configuration features such as acquisition mode (HiRes), cursor
gating, coupling, and BW limits are applied uniformly across a group of
measurements.
■
Programmatic interface command support.
The key measurements of DPOPWR include the following:
■
Switching Loss measurement computes TON, TOFF, and total loss values
and trajectory plot of ON and OFF values for all switching cycles.
■
Hi Power Finder identifies all the peaks in the power waveform (MATH) and
has interactive detail results. It allows traversing between the peak values and
the result shows energy and loss values for each ON-ON switching cycle.
■
RDS(on) and SOA, measures dynamic internal resistance and customizable
Safe Operating Area mask testing with linear and log scales. SOA X-Y
RDS(on) does not support reference waveforms.
■
Magnetics measurements compute total magnetic loss, inductance of core and
shows graph of relationship between B and H.
■
Power Quality measurement, computes THD, True Power, Apparent Power,
Power Factor, and Crest Factor. All these analysis outputs are shown in a
quick view in the Summary results table.
■
Current Harmonics enables all precompliance testing to cover EN61000-3-2,
EN61000-3-2 AM14, and MIL 1399 (400 Hz) standards. User defined mode
displays up to the 100th harmonic in both table and bar graph formats.
■
Voltage Harmonics provide a frequency-domain view of the AC voltage,
such as at the output of an inverter.
■
Inrush current measurement identifies the peak currents based on configured
threshold level.
■
Capacitance measurement computes peak capacitance value above
configured threshold value.
■
Timing/Modulation analysis displays a time-trend plot of the cycle-to-cycle
variations in the modulated switching signal based on positive and negative
pulse width, positive and negative duty cycle, frequency, period, and skew
measurements.
■
Amplitude measurement computes High, Low, High-Low, Cycle Min, Cycle
Max and Cycle Pk-Pk. All these analysis outputs are shown in the Results
table, Time trend, and Histogram plots.
