Temperature coefficient (0°C–18°C and 28°C–50°C): ±(0.15 × accuracy specification)/°C.
Maximum output power and source/sink limits:
2
30.603W per channel maximum. ±1.515A at ±20.2V, ±101mA
at ±202V, four-quadrant source or sink operation.
Current regulation: Line: 0.01% of range. Load: ±(0.01% of range + 100pA).
Voltage limit/compliance:
6
Bipolar voltage limit (compliance) set with a single value. Minimum value is 10mV.
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: <70ȝs 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: <50ȝs typical. 20V range: <110ȝs typical. 200V range: <700ȝs 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: <120ȝs typical (Rload >6ȍ).
100mA–10mA ranges: <80ȝs typical.
1mA range: <100ȝs typical.
100ȝA range: <150ȝs 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.
