When you adjust the Performance slider, the instrument adjusts settings based on where you position
the slider. As you increase speed, you lower the amount of resolution. As you increase resolution, you
decrease the reading speed. The settings that the instrument adjusts include autozero, autodelay and
filter settings, display digits, NPLC, and source readback. These settings take effect the next time the
output is turned on and measurements are made.
Source menu
The menus organized under Source in the main menu allow you to select, configure, and perform
source and sweep operations from the front panel. The following topics describe the settings that are
available on these interactive screens.
Source Settings menu
You can change the following settings by pressing the
MENU
key and selecting Source

Source Range
Set the source range for the selected source function. For more

states. For more information, see
Overvoltage
Protection Limit
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 4-34).
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 5-24).
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. Turn off this setting to
increase measurement speed. For more information, see
(on page 4-44).
Source Delay
Set a delay for the selected source function. This delay is in
addition to normal settling times. Select
Auto Delay
to have the
instrument automatically set the delay, or select
Specify Delay
to
enter a value. For more information, see
(on page 4-46).
