Click here for details on the Temperature Settings:
(This is the Drop-down Hotspot)-
Hot Plate IP Address: From the appendix, “Configure the InTEST Thermal Platform Controller.”

-
Click the DONE button dialog header to accept the settings and close the dialog.
Configure IV and CV Measurement Control Settings
After you have set up the General Settings, configure the IV and CV measurement settings and choose specific tests:
-
Select IV and CV Measurement Control on the left side of the screen.
-
(Optional) Select the Offline Mode (formerly Demo Mode) checkbox run a demonstration program. See IV and CV Offline Mode for more information.
-
Select DUT - Choose IGBT, FET from the drop-down list.
-
Available tests depend on the DUT, the test type, the Instrument option (set in the IV and CV Hardware Configuration Screen and the type of SMU available).
-
If you are using a B1505A power device analyzer, you must also select the test type:
- IV
- CV
- Gate Diode
-
-
Temperature Control Mode - Choose a setting based on whether you have a thermal platform or not:
- The B1506A power analyzer uses the InTEST thermal platform, model HP289-PM, which is available separately (contact: www.inTESTthermal.com).
- The B1505A also requires the Keysight N1265A text fixture to work with the InTEST platform.
- Keysight recommends that you set up the measurement conditions and confirm that you can make successful measurements at normal room temperature before you run the tests with the thermal platform.-
Fully Remote: Enter the temperature(s) you want tested in the temperature field, separated by semicolons (;). The software automatically heats the test chamber and triggers the measurements when each temperature is reached.
-
Temperature Trigger:
-
Enter the temperature(s) you want tested in the temperature field, separated by semicolons (;).
-
Finish selecting tests and setting up the device parameter information for each test, as described below.
-
Manually heat the test chamber to more than the highest value you entered and then stop heating the chamber.
-
Start the test. The software automatically triggers measurements when the test chamber cools to each value that you entered.
This method takes longer (on the order of hours) because of the time required for the test chamber to cool between each measurement.
-
-
Manual: Use this option if you have your own thermal control solution, or do not plan to use the thermal platform.
- If you have your own thermal control solution:
Enter a single value for the temperature at which you want to run the test.
Finish selecting tests and setting up the device parameter information for each test, as described below.
Use your thermal controller to heat the test chamber to the temperature value you entered.
When the chamber reaches the correct temperature, run the test manually as described below.
Repeat this procedure to run additional tests at different temperatures, as needed.
-
If you do not have a thermal platform or plan to make room-temperature tests only:
-
Enter the average temperature of the room in which you perform the tests. (If you don't know the average temperature, use 25 °C as a typical value.)
-
Finish selecting tests and setting up the device parameter information for each test, as described below.
-
Run the test manually as described below.
-
- If you have your own thermal control solution:
-
-
Select the checkbox for each test that you want to run. The tests displayed depend on whether you have chosen IGBT or FET for the DUT.
You can also select all available tests:
-
Click on the name for each test to display a diagram for the test and to fill out test parameters.
When filling out parameter values, do not exceed the device limits specified in the product data sheet.-
For IGBT devices, go here for help with parameters for each test.
-
For FET devices, go here help with parameters for each test.
For example, if you have an IGBT DUT and have selected the Cies test, clicking on the test name displays the following diagram and configurable parameters:
For examples of filling out test parameters, see Setting IV and CV Test Parameters.
-
Save Settings for Re-use
(Optional) To save set-up time, you can save all configuration settings and general settings to a file that you can re-use to skip the configuration process.
-
Click on Settings on the main screen.
- Select Save Settings to File. This displays a file save dialog.
-
Use the dialog to browse to the directory where you want to store the settings.
-
Type a file name for the settings file using one of the following filenames:
- IVCV.kts - for IV-CV tests
- ONSTATE.kts - for on-state S-parameter tests
- OFFSTATE.kts - for off-state S-parameter tests
-
Click Save. This saves your current PD1000A settings into a Keysight Test Settings file (.kts).
