HIGHLIGHTS
Input Measurements
- Power quality: Real power, apparent power, reactive power, power factor, crest factor (V & I), phase angle
- Current harmonics (based on IEC 61000-3-2 up to the 40th harmonic)
- Inrush current
Switching Measurements
- Rds-on & Vce-sat
- Switching loss (power & energy)
- Slew rate (dv/dt & di/dt)
- Modulation (duty cycle, pulse-width, period, frequency, etc., versus time plot)
Output Measurements
- Output ripple
- Turn-on/turn-off time
- Transient response time
- Efficiency
Frequency Response Measurements
- Power supply rejection ratio (PSRR) – Bode
- Control loop response – Bode (automatically measures phase margin and gain margin)
The power software package for Keysight’s InfiniiVision 6000 X-Series oscilloscopes enables a broad range of automated power supply characterization measurements including critical frequency response measurements such as power supply rejection ratio (PSRR) and control loop response. This package also enables hardware-based pass/fail mask testing and USB PD triggering and decode.
