Description
Source Range
Set the source range for the selected source function. For more
information, see Source range.
Output Off State
Select from Normal, Hi Impedance, Zero, and Guard output-off
states. For more information, see
(on page 2-82).
High Capacitance
Turn on this setting to minimize overshoot, ringing, and instability
when measuring low current while driving a capacitive load. For
more information, see
(on page 4-21).
Source Readback
Turn on this setting to have the instrument record and display the
actual value of the source, instead of the programmed value. Using
source readback results in more accurate measurements, at the
cost of a reduction in measurement speed. For more information,
see
(on page 2-110).
Overvoltage
Protection
Set the overvoltage protection setting of the source output to
restrict the maximum voltage level that the instrument can source.
For more information, see
(on page 2-98).
Source Delay
Set a delay for the selected source function. This delay is in
addition to normal settling times. For more information, see
(on page 2-112).
