Parameter list#

Executes all child tests for each parameter in the parameter list.

Description#

Executes all child tests for each parameter in the parameter list. The parameter list is a list of semicolon separated numbers. The parameter value can be accessed in the child tests by using the output parameter value as variable input. Child tests can be added by dragging and dropping tests from the test picker onto the Parameter list sequence.

Input parameters#

Parameter Description
Parameter list Semicolon separated list of numbers.

Output parameters#

Parameter Description
value The parameter value of the current iteration

Example#

Goal:

Performing a voltage sweep using the generic smu tests and parameter list sequence.

    end

Hardware setup:

Connect a supported SMU to the computer running Measmatic over TCP/IP.

In the device manager add the SMU to the current test site configuration. Change the name, the IP address in the device properties of the device.

Connect a 100 ohm resistor between the high and low terminal of the SMU.

Measmatic setup:

  1. Add a new Parameter list sequence to the test sequence by dragging and dropping a Parameter list from the test picker into the test sequence. Set the Parameter list input to 0;0.5;1;1.5;2;2.5
  2. Then add a SMU output on test under the Parameter list. Set the Device in the SMU output on test to be the SMU added in the device manager. Set the Mode to Voltage, Limit to 100mA and Range to Auto. Set the Level to the value output parameter of the Parameter list test by clicking on the VAR button next to the input field and selecting the corresponding value.
  3. Also add a SMU output measure test under the Parameter list after the SMU output on test and set the Device to the SMU.
  4. Finally, the SMU output off test must be added under the Parameter list after the SMU output measure test. Set the Device to the SMUs.
  5. Execute the test sequence by pressing the Run all tests button.

Under the SMU output measure test you will see the measured voltage and current for each parameter value in the parameter list.
