Table A-1 lists the specifications of the dc source. Specifications are warranted over the ambient
temperature range of 0 to 55 °C. Unless otherwise noted, specifications apply when measured at the rear
terminals after a 30-minute warm-up period.

For Agilent 66312A: appliesinSCPI mode, withcurrent detector settoDC. With current detectorset to ACDC, accuracy is 0.2% + four times
the fixed error value. InCOMPatibility mode, accuracyis 0.2% + six times the fixed error value.
