To make an ohms measurement:
1. Press the SRC key to select the source function.
2. Set the output source (current or voltage, dependent on which function is selected) to a value
based on the expected resistance. See Step 1: Select and set the source level (on page 4-30).
3. Press the LIMIT key to edit the voltage or current limit. When programming a voltage limit, set the
voltage limit above the maximum expected voltage across the resistor under test. When
programming a current limit, set the current limit at or above the maximum expected current
through the resistor under test. See Step 2: Set the compliance limit (on page 4-30).
4. Press the MEAS key to display voltage or current.
5. Make sure that AUTO measurement range is on (press the AUTO key if needed).
6. Press the MEAS key as many times as needed to display ohms.
7. Press the OUTPUT ON/OFF control to turn the output on.
8. View the displayed reading (press the TRIG key if necessary). When finished, press the OUTPUT
ON/OFF control again to turn the output off.
Remote ohms command
Use the smua.measure.r() function to get a resistance reading. The programming example below
illustrates how to get a resistance reading:
reading = smua.measure.r()
See Remote source-measure commands (on page 4-31) for more commands to set up source and
measure functions, and Introduction to TSP operation (on page 9-1) for more details.
Ohms programming example
The following programming example illustrates the setup and command sequence of a typical ohms
measurement procedure with the following parameters:
• Source function: current, 10 mA range, 10 mA output
• Voltage measure range: auto
• Voltage compliance: 10 V
• Sense mode: 4-wire
-- Restore 2601B-PULSE defaults.
smua.reset()
-- Select current source function.
smua.source.func = smua.OUTPUT_DCAMPS
-- Set source range to 10 mA.
smua.source.rangei = 10e-3
-- Set current source to 10 mA.
smua.source.leveli = 10e-3
-- Set voltage limit to 10 V.
smua.source.limitv = 10
-- Enable 4-wire ohms.
smua.sense = smua.SENSE_REMOTE
