SOURCE LIMITS: Voltage Source Current Limit: Bipolar current limit set with single value. Min. 10% of range.
Current Source Voltage Limit: Bipolar voltage limit set with single value. Min. 10% of range.
OVERSHOOT: Voltage Source: <0.1% typical (full scale step, resistive load, 20V range, 10mA I-Limit.
Current Source: <0.1% typical (1mA step, R
Load
= 10kW, 20V range)
VOLTAGE SOURCE: Noise 10Hz–1MHz (RMS): 2mV typical into a resistive load.
OVER VOLTAGE PROTECTION: User selectable values, 5% tolerance. Factory default = none.
