Load and line regulation ± (% of output + offset)

Voltage

< 0.01% + 3 mV

Current

< 0.01% + 250 μA

Ripple and noise (20 Hz to 20 MHz)

Normal mode voltage

< 5 mVpp/0.5 mVrms for 8 V/20 V models

< 8 mVpp/1 mVrms for 35 V/60 V models

Normal mode current

< 4 mArms

Common mode current

< 1.5 μArms

Programming

Voltage

< 0.05% + 10 mV (< 0.1% + 25 mV for output 2 of E3646/47/48/49 A)

Current

< 0.2% + 10 mA

Readback (over GPIB and with respect to actual output)

Voltage

Resolution

Program

< 5 mV/1 mA

Readback

< 2 mV/1 mA

Meter

10 mV/1 mA

Transient response

Less than 50 μsec for output to recover to within 15 mV following a change in output current from full

load to half load or vice versa.

< 90 msec

OVP

Accuracy,

± (% output + offset)

< 0.5% + 0.5 V

< 1.5 msec, OVP ¥3 V/< 10 msec, OVP < 3 V

1. Accuracy specifications are valid after a 1-hour warm-up with no load and calibration at 25 ºC.

2. Meter accuracy specification is at minimum 10 mV decimal limited by front panel resolution.

3. Maximum time required for the output voltage to change from 1% to 99% or vice versa following the receipt of VOLTage or APPLy command via direct GPIB

or RS-232 interface.

4. Average time for output to start and drop after an OVP condition occurred.
