Output Voltage Ripple & Noise (PARD) from 20 Hz – 20 MHz:
Measured at the output terminals, under all load conditions, in Voltage Priority mode. Output Bandwidth setting
= Low
CV peak-to-peak 12 mV 12 mV 15 mV
CV rms 1.2 mV 1.2 mV 1.5 mV
Load Effect (Load regulation):
For any load change, with a lead drop of 1.0 V. The load lead drop reduces the maximum available voltage at the
load.
