    The Application Test mode shown in figure 1-6 is a pre-defined test library coming with the B1505A and it includes a basic and frequently used test, for example, Id-Vd measurements. The user can start measurements by just typing in the measurement parameters and the test results with a proper data which is automatically extracted by the measurement is coming out by just pressing the Measure button.

    Classic Test mode Classic Test is used inside of the Application Test definition as a main measurement engine for defining and executing a test. Classic Test can be used itself as a stand- alone test engine and it can define a unique test. The user interface of the Classic Test mode adopts the same concept of the Agilent Semiconductor Parameter Ana- lyzers and anyone can get used to handle this interface easily.

Set Unit field appropriately depending on your B1505A and connection set- ups. If your B1505A is one HCSMU configuration (Note: maximum two HCSMUs are allowed in the configuration), set HCSMU to the collector supply as in the case of the example setup.

Review: The voltage and the current measurement accuracy of HVSMU in 1mA and 200 V range used in the application is better than 0.03 %. Therefore, the measured accu- racy of the resistor can be expected to be better than approximately 0.05% (~ SQRT (0.03^2 + 0.03^2).
