ADDITIONAL SOURCE SPECIFICATIONS
COMMAND PROCESSING TIME: Maximum time required for the output to begin to change following the receipt of :SOURce:VOLTage|CURRent
<nrf> command. Autorange On: 10ms. Autorange Off: 7ms.
OUTPUT SETTLING TIME (typical to 10% of final value): <2s, 1pA and 10pA ranges; <50ms, 100pA through 10nA ranges; <5ms, 100nA through
100mA ranges.
OUTPUT SLEW RATE: 30V/ms, any V range, 10mA compliance.
COMMON MODE VOLTAGE: ±42VDC maximum.
4-WIRE SENSE: Up to 1V drop per load lead, 10
Ω
maximum per sense lead, 100µA range and up. For details on using 4-wire sense with the 10µA
range and below, refer to the User ’ s Manual.
OVER TEMPERATURE PROTECTION:
Internally sensed temperature overload puts unit in standby mode.
RANGE CHANGE OVERSHOOT: Overshoot into a fully resistive 100k
Ω
load, 10Hz to 1MHz BW, adjacent ranges, 100mV typical, except 20V/200V
range boundary.
MINIMUM COMPLIANCE VALUE: 0.1% of range.
