Keysight's InfiniiVision 4000 X Series oscilloscope software package enables a wide range of automated measurements to characterize power supplies , including critical frequency response measurements such as: B. Power Supply Rejection Ratio (PSRR) and control loop behavior. This package also enables hardware-based pass / fail mask testing and USB PD triggering and decoding.
Input measurements:
- Network quality: active 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
Circuit measurements:
- Rds-on and Vce-sat
- Switching losses (power and energy)
- Rate of rise (dv / dt and di / dt)
- Modulation (duty cycle, pulse width, period, frequency, etc., over time)
Output measurements:
- Output ripple
- Switch-on / switch-off time
- Settling time
- Efficiency
Frequency response measurements:
- Power supply rejection ratio (PSRR) - Bode
- Control loop response - Bode (automatically measures phase margin and gain margin)
