The HP‑01 is a laboratory trainer specifically designed for the detailed study and measurement of hybrid parameters (h-parameters) of a bipolar junction transistor (BJT) in common base, common emitter, and common collector configurations. This trainer is ideal for electronics engineering students, helping them understand small-signal models and transistor behavior under AC analysis.

The setup includes onboard biasing circuitry, test points, and measuring sockets to allow students to connect multimeters or CROs to measure input impedance, output admittance, current gain, and voltage gain. The unit also includes clearly labeled circuitry, component placement, and a supplied transistor under test, making it convenient for both demonstration and hands-on experimentation.
