Output Characteristics
Temperature coefficient (0 °C to 18 °C and 28 °C to 50 °C):
±(0.1 x Accuracy specification) /°C.
Max output power and source/sink limits:
31.8 W
±6 V@ ±3.03 A, ±21 V@ ±1.515 A, ±210 V@ ±105 mA, four quadrant
source or sink operation.
Output location: Channel 1 at front, and channel 2 at rear.
Output connectors:
Banana jack. Triaxial connections are recommended for sourcing less than
1 nA. A banana jack to triaxial adapter is available for low current source.
Low terminal connection: Chassis grounded or floating
Sensing Modes: 2-wire or 4-wire (Remote-sensing) connections
Maximum load:
Normal mode: 0.01 μF
High Capacitance mode: 50 μF
DC floating voltage: Maximum ±250 V DC between low force and chassis ground.
Guard offset voltage (V source): <4 mV
Remote sense operation range:
Maximum voltage between High Force and High Sense = 3 V
Maximum voltage between Low Force and Low Sense = 3 V
Common mode isolation: >1 GΩ, <4500 pF
Maximum sense lead resistance: 1kΩ for rated accuracy
Sense input impedance: >10 GΩ
Current limit/compliance:
Accuracy is same as current source. Minimum value is 1 % of range, or 1 nA
in 10 nA range.
Voltage limit/compliance:
Accuracy is same as voltage source. Minimum value is 1 % of range, or 20
mV in 200 mV range
Over range:
101 % of source range for 1.5 A and 3 A ranges. 105 % of source range other
than 1.5 A and 3 A ranges. No over range for 200 V range with current
exceeding 105 mA pulse only condition.
Over temperature protection:
Output turns off then resets at over temperature sensed internally.
Voltage Source:
Settling time:
Time required to reach 0.1 % of final value at open load condition.
Step is 10 % to 90 % range.
Voltage Range Settling Time
200 mV < 50 µs
2 V < 50 µs
20 V < 110 µs
200 V < 700 µs
