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, when changing from 10% to 90%
of range, after source level command is processed on a fixed range.
100mV, 1V ranges: <50ȝs typical.
6V Range: <100ȝs typical.
40V Range: <150ȝs typical.

Current source output settling time: Time required to reach 0.1% of final value, when changing from 10% to 90%
of range, after source level command is processed on a fixed range. Values below for Iout · Rload = 1V
unless noted.
3A–10mA ranges: <80ȝs typical (current less than 2.5A, Rload >1.5ȍ).
1mA range: <100ȝs typical.
100ȝA range: <150ȝs typical.
10ȝA range: <500ȝs typical.
1ȝA range: <2.5ms typical.
100nA range: <25ms typical.
DC floating voltage: Output can be floated up to ±250VDC from chassis ground.
Remote sense operating range:
1
Maximum voltage between HI and SENSE HI = 3V.
Maximum voltage between LO and SENSE LO = 3V.
Voltage output headroom:
40V range: Max. output voltage = 42V – total voltage drop across source leads (maximum 1ȍ per source lead).
6V range: Max. output voltage = 8V – total voltage drop across source leads.
Over temperature protection: Internally sensed temperature overload puts unit in standby mode.
Voltage source range change overshoot: Overshoot into a 100kȍ load, 20MHz BW, 300mV typical.
Current source range change overshoot: <5% of larger range + 300mV/Rload typical.
(see “CURRENT SOURCE OUTPUT SETTLING TIME” for additional test conditions).
5 Add 150ȝs when measuring on the 1A range.
