B1112 – OPERATIONAL AMPLIFIER TRAINER The trainer is implemented in a modular form and covers the subject of Operational Amplifiers, from the fundaments to parameter measurement techniques and to selected practical circuit applications. The trainer consists of a collection of boxlike modules, 100 x 160 x 20mm size, with a magnetic base and a printed circuit board front face. The PCB face includes the components and devices needed to perform the experiments, with clear silk-printing indicating the components symbols, identities and interconnections.
(Base plate, 430 x 310 x 30 mm) where they are retained by the magnetic base. The connections to the power supply and to the measuring instruments are by plug-in cables. Certain experiments require more than a single module to be interconnected. This is also done by plug-in cables. The magnetic latching of the modules to the metallic Base plate ensures that the various items remain steadily fixed even if the Base plate is placed vertically, as in case of collective demonstrations by the Instructor.
For the execution of the experiments the modules are placed on a metallic plate
