Requesting readings
You can request readings by including the appropriate measurement command as the argument for
the
print()
command. The following programming example illustrates how to request a Channel A
current reading:
print(smua.measure.i())
Source-measure programming example
The following programming example illustrates the setup and command sequence of a basic
source-measure procedure with the following parameters:
•
Source function and range: voltage, autorange
•
Source output level: 5 V
•
Current compliance limit: 10 mA
•
Measure function and range: current, 10 mA
