Source Settings menu
You can change the following settings by pressing the MENU key and selecting Source Settings.
Setting 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 Output-off state (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
High capacitance operation (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
Source readback (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
Overvoltage protection (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 Setting
the source delay (on page 2-112).
