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

-- Restore Series 2600B defaults.

smua.reset()

-- Select voltage source function.

smua.source.func = smua.OUTPUT_DCVOLTS

-- Set source range to auto.

smua.source.autorangev = smua.AUTORANGE_ON

-- Set voltage source to 5 V.

smua.source.levelv = 5

-- Set current limit to 10 mA.

smua.source.limiti = 10e-3

-- Set current range to 10 mA.

smua.measure.rangei = 10e-3

-- Turn on output.

smua.source.output = smua.OUTPUT_ON

-- Print and place the current reading in the reading buffer.

print(smua.measure.i(smua.nvbuffer1))

-- Turn off output.

smua.source.output = smua.OUTPUT_OFF
