  • Product Information
  • Detailed Specifications

When using the network analyzer to measure impedance, such as the capacitance and ESR or a capacitor, or the DCR of an inductor, etc., it is often necessary to provide a voltage bias to the device being tested.  This is true of semiconductor junction capacitances, varactors, and some ceramic capacitors (especially X5R).  In these cases the impedance is a function of the DC bias on the device. The Picotest DC bias injector (J2130A) is used for this purpose during impedance measurements.

  • 10Hz-10MHz usable bandwidth Low loss design
  • Easily measure varactors, junction capacitance
  • Measure X5R capacitor voltage sensitivity
  • Bias low power transistor amplifiers and diodes for parameter extraction
