Display screen
The front panel displays source-measure values and readings or user-defined messages. The display
screen options include:
• Source-measure, compliance screens: Display SMU source-measure readings and
compliance values.
• User screen: Display user-defined messages and prompts.
Configure the type of source-measure and compliance displayed by setting the display.screen
attribute. The following programming example illustrates how to display source-measure and
compliance values, and measure readings for SMU A:
display.screen = display.SMUA
Measurement functions
With a source-measure screen selected, the measured reading can be displayed as volts, amperes,
ohms, or watts. Configure the type of measured reading displayed by setting the
display.smua.measure.func attribute. The following programming example illustrates how to
display ohms measurements:
display.smua.measure.func = display.MEASURE_OHMS
Limit functions
When the pulser is disabled, the displayed limit value is either the primary limit value (current or
voltage) or the power limit value. Configure the type of limit function that is displayed by setting the
display.smua.limit.func attribute. The following programming example illustrates how to
display the power limit setting:
display.smua.limit.func = display.LIMIT_P
When the pulser is enabled, the sense and source protection levels are displayed. Use the LIMIT key
to switch between the sense and source protection level.
Display resolution
Display resolution for measured readings can be set to 4-1/2, 5-1/2 or 6-1/2. Configure the type of
resolution displayed by setting the display.smua.digits attribute. The following programming
example illustrates how to set 5-1/2 digit resolution for measured readings:
display.smua.digits = display.DIGITS_5_5
Display trigger wait and clear
To set the instrument to wait for the front-panel TRIG key to be pressed, send the
display.trigger.wait() function. To clear the trigger event detector, send the
display.trigger.clear() function.
