E3631A/32A/33A/34A Programmable DC Power Supply Specifi cations
1
Accuracy specifi cations are valid after a 1-hour warm-up and calibration at 25 ºC.
2
Accuracy refers to readback over GPIB and RS-232 or front panel with respect to actual output.
3
Maximum time for output to change after receipt of commands.
