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
Accuracy
1
12 months (@ 25 ºC ± 5 ºC), ± (% output + offset)
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 < 0.05% + 5 mV (< 0.1% + 25 mV for output 2 of E3646/47/48/49 A)
Current < 0.15% + 5 mA (< 0.15% + 10 mA for output 2 of E3646/47/48/49 A)
Meter
2
(over front panel with respect to actual output)
Voltage < 0.05% + 2 counts (<0.1% + 4 counts for output 2)
Current < 0.15% + 5 mA (<0.15% + 10 mA for output 2)
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.
1. Accuracy specications are valid after a 1-hour warm-up with no load and calibration at 25 ºC.
2. Meter accuracy specication is at minimum 10 mV decimal limited by front panel resolution.
