The Keysight D4000PWRB 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 decoding.

• Input Measurements
• Power quality: Real power, apparent power, reactive power, power factor, crest factor (V and I), phase angle
• Current harmonics (based on IEC 61000-3-2 up to the 40th harmonic)
• Inrush current
• Switching Measurements
• Rds-on and Vce-sat
• Switching loss (power and energy)
• Slew rate (dv/dt and 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)
