POWER ANALYZER OPTION
Power Analyzer Automates Switching Device Loss Measurements
Quickly measure and analyze the operating characteristics of power conversion
devices and circuits with the Power Analyzer option. Critical power switching de-
vice measurements, control loop modulation analysis, and line power harmonic
testing are all simplied with a dedicated user interface and automatic measure-
ments. Areas of turn-on, turn-off, and conduction loss are all identied with color-
coded waveform overlays for faster analysis.
Power Analyzer provides quick and easy setup of voltage and current inputs and
makes measurements as simple as the push of a button. Tools are provided to
help reduce sources of measurement errors and the measurement parameters
provide details of single cycle or average device power losses.
Beyond the advanced power loss measurement capabilities,
the Power Analyzer modulation analysis
capabilities provide insight to
understand control loop response
to critical events such as a power
supply’s soft start performance
or step response to line and load
changes. The Line Power
Analysis tool allows simple and
quick pre-compliance testing
to EN 61000-3-2.
Teledyne LeCroy has a variety of probes
and probing accessories such as high
common mode rejection ratio (CMRR)
differential ampliers, differential probes,
current probes, and deskew xtures.
