Temperature coefficient (0°C–18°C and 28°C–50°C): ±(0.15 × accuracy specification)/°C.
Maximum output power and source/sink limits:
at ±202V, four-quadrant source or sink operation.
Current regulation: Line: 0.01% of range. Load: ±(0.01% of range + 100pA).
Voltage limit/compliance:
Accuracy same as voltage source.
Overshoot: <0.1% typical (step size = 10% to 90% of range, resistive load; see "Current source output settling
time" for additional test conditions).
Additional Source Specifications
Transient response time: <70 s for the output to recover to 0.1% for a 10% to 90% step change in load.
Voltage source output settling time: Time required to reach 0.1% of final value after source level command is processed on a
fixed range.
200mV, 2V ranges: <50 s typical. 20V range: <110 s typical. 200V range: <700 s typical.
Current source output settling time: Time required to reach 0.1% of final value after source level command is processed on a
fixed range. Values below for Iout · Rload = 2V unless noted.
1.5A–1A ranges: <120 s typical (Rload >6 ).
100mA–10mA ranges: <80 s typical.
1mA range: <100 s typical.
100 A range: <150 s typical.
4 Accuracy specifications do not include connector leakage. Derate accuracy by Vout/2E11 per °C when operating
between 18°C–28°C. Derate accuracy by Vout/2E11 + (0.15 * Vout/2E11) per °C when operating <18°C and >28°C.
5 10A range accessible only in pulse mode.
6 For sink mode operation (quadrants II and IV), add 10% of compliance range and ±0.02% of limit setting to corresponding
voltage source specification. For 200mV range add an additional 120mV of uncertainty.
Specifications are subject to change without notice.
