Supply sources: mains supply, mains switches, transformers, means of interference suppression (suppression capacitors, suppression chokes, suppression elements). Supply voltage distribution: supply distribution in instrument housing and on printed circuit boards, distribution in the ground, galvanic separation of systems (impulse tranformers, optrons).
Parasitic events and their suppression: coupling in input and outtput circuits, coupling on line resistances, parasitic capacitances and inductances, transient resistances, thermoelectric voltage, overvoltage on inductive load.
Signal transmission over long lines: reflections in the lines, crosstalk, charging and discharging the lines.
Electric and magnetic field screening: electric field screening of systems and lines, magnetic field screening of systems and lines. Equipotential guarding: insulation ring guarding, teflon support point, examples of active insulation of critical points.
Selection of discrete components and application recommendation: resistors, potentiometers and potentiometric trimmers, capacotors and capacitive trimmers, inductors, diodes, transistors (bipolar, unipolar; power, HF).
Application recommendation for analog and digital integrated circuits: operational and transimpedance amplifiers, analog multiplexersand demultiplexers, comparators and timers, D/A and A/D converters, digital integrated circuits, microprocessors.
Mechanics design: regulation and control elements and their lay-out, communication and indication elements, lay-out of regulation and communication elements on the front panel of the instrument, graphic and technical aspects of the mechanical part of design, design of instrument housing.
Mechanical resistance of devices: resistance to shocks, vibration, moisture, water; abstraction of heat from the device, cooling elements, temperature stabilization (thermostatic control).
