Maximum Reverse Bias Current:	With AC input power applied and the dc output reverse
	biased by an external dc source, the supply will continuously
	withstand without damage a current equal to its output
	current rating (see Table 1- 1a).
Remote Sensing Capability
Voltage Drop Per Lead:	Up to 1/2 of rated output voltage.
Load Regulation:	Add 3 mV to spec (see Table l-la) for each l-volt change in
	the + output lead due to load current changes.
Load Voltage:	Subtract voltage drop in load leads from specified output
	voltage rating.

Command Processing Time (Average time for output voltage to change after receipt of digital data when the supply is connected directly to the GPIB Bus):

				20 ms
Downprogrammer Current Capability (± 15%):	5.8 A	2.5 A		1.5 A	0.9 A	0.75 A
Output Voltage Programming Response Time
Rise/Fall Time (time for output to change from 90 % to 10% or from 10% to 90% of its total excursion):
Settling Time (time for output change to settle within	<15 ms
	1 LSB (0.025% x rated voltage) of its final value):
	<60 ms
Monotonicity:	Output is monotonic over entire rated voltage, current, and
	temperature range.
Auto-Parallel Configuration:		Up to 3 identical models
Analog Programming (IP & VP)
Input Signal:*				0 to -5 V
Input Impedance:			10 kΩ, nominal
*Signal source must be isolated.
Current Monitor Output (+IM):	0 to -5 V represents zero to full-scale current output
Savable States
Nonvolatile Memory Locations:			5 ( 0 through 4)
Nonvolatile Memory Write Cycles:			40,000, typical
Prestored State (factory default):				Location 0
