Section 12: TSP Fundamentals and Script Management
Assuming SMU A output is on, it will output 2V and measure the current. The current reading is
sent to the host PC and displayed.
Interactive scripts
An interactive script prompts the operator (via the SourceMeter instrument's display) to input test
parameters (via the SourceMeter instrument's front panel). The chunk fragment below uses display
messages to prompt the operator to select an SMU Channel (A or B), a source function (I or V), and
to input the source level. When an input prompt is displayed, the script will wait until the operator
inputs the parameter and/or presses the ENTER key.
The
display.prompt
value is not entered, the default level (1mA or 1V) will be set when ENTER is pressed. The
operator will not be able to input values that are not within the minimum (0.5mA or 0.1V) and
maximum (3mA or 10V) limits.

--Wait for operator to set source level:

chan.source.leveli = level
