Analyzing a BJT

Complete the following steps to run current-voltage (IV) analyses for a BJT:

  1. Launch the IV Analyzer Soft Front Panel (SFP).
  2. Select Transistor under Analyzer mode.
  3. Connect a BJT to the IV ANALYZER terminals on the NI ELVIS III. Attach its collector to DUT+, its base to BASE, and its emitter to DUT-. This is shown in the Connections diagram under Analyzer & hardware on the SFP.
    Note Insert the component directly into the IV Analyzer screw terminals to achieve the highest accuracy measurements. In cases where the component cannot be directly inserted, use short wires to minimize parasitic effects that impact the overall impedance of the device under test.
  4. Select NPN or PNP under Transistor type.
  5. Adjust the parameters as desired.
  6. Click the Run button.
  7. Use the cursors to take measurements.
    Note You may hear clicking sounds from the NI ELVIS III while operating the SFP. This is expected behavior and is due to the switching of internal relays.
