Agilent Technologies E3631A guide

Chapter 1 Specifications

Supplemental Characteristics

Cooling

Fan cooled

Operating Temperature

0 to 40°C for full rated output. At higher temperatures, the output current is derated linearly to 50% at 55°C maximum temperature.

Output Voltage Overshoot

During turn-on or turn-off of ac power, output plus overshoot will not exceed 1 V if the output control is set to less than 1 V. If the output control is set to 1 V or higher, there is no overshoot.

Programming Language

SCPI (Standard Commands for Programmable Instruments)

State Storage Memory

Three (3) user-configurable stored states

Recommended Calibration Interval

1 year

Dimensions*

212.6mmW x 132.6 mmH x 348.2 mmD (8.4 x 5.2 x 13.7 in) *See the next page for detailed information.
