Specifications

Table A-1 lists the specifications of the dc source. Unless otherwise noted, specifications are warranted
over the ambient temperature range of 0 to 55 °C. Specifications apply with typical cellular phone
capacitive loads from 0µF to 12,000µF. Sensing is at the rear terminals of the power supply after a 30-
minute warm-up period. Sense terminals are externally jumpered to their respective output terminals.

4 Agilent 66111A units do not have a low current range, the dc measurement accuracy applies from 0 amperes to the rated current.
5 Applies with current detector set to DC. ACDC mode accuracy is 0.2% + 3mA for sourcing and 0.2% + 3.6 mA for sinking.
6 This specification may degrade slightly when the unit is subjected to an RF field ≥3 V/meter.
7 Specification is for phone capacitance greater than 6µF.
8 Applies to the negative portion of the output voltage transient waveform, following a 0.1 A to 1.5 A load current change.
(Applies with unit set to High capacitance compensation range with 5 µF minimum output load capacitance.)
9 Following a 0.75 A to 1.5 A load change.
