10 A range: <500 s typical.
1 A range: <2ms typical.
100nA range: <20ms typical.
DC floating voltage: Output can be floated up to ±250VDC from chassis ground.
Remote sense operating range:
SENSE LO = 3V.
Voltage output headroom:
200V range: Max. output voltage = 202.3V; total voltage drop across source leads (maximum 1 per source lead).
20V range: Max. output voltage = 23.3V; total voltage drop across source leads (maximum 1 per source lead).
Over temperature protection: Internally-sensed temperature overload puts unit in standby mode.
Voltage source range change overshoot: Overshoot into a 200k load, 20MHz BW, 300mV typical.
Current source range change overshoot: <5% of larger range + 300mV/Rload + 60nA typical (see "Current source output
settling time" for additional test conditions).
