SMTE281 Analogue Electronics Experiment Kit Didactic Training School Laboratory Training Electrical Training Equipment 1 Product Introduction: Analog circuit experiment box make all the experiment module concentrated distributed on the circuit board, lead out the down-lead through the locking type jack, student can set up circuit by themselves according to experiment project, it can cultivate the ability of thought and start work, it also enhance the applicability of this experiment box. Analog circuit experiment box is based on the teaching experiment of “ higher technical school fundamentals of electronic technology basic requirements of the course teaching” including all the experiment content of “ basis of analogue electronic technique” it is the last type experiment machine for the electronic technique, electronic circuit and other course of institutions of higher education, secondary specialized school and TVET university. 2 Experiment box content 1. Power supply: input: AC 220V±10%,50HZ Output: DC: - 5V～-12Vadjustable, I≥0.2A DC: ＋5V～＋27Vadjustable ,DC I≥0.2A DC: ±12V,+5V,DC I≥0.2A The above circuit have overcurrent protection, self-recovery function AC V:7.5V×2；AC I≥0.15A 2. Adjustable DC signal source: Twin channel-0.5V～＋0.5V, －5V～＋5V two gear continuously adjustable. 3. Low frequency signal source: 2HZ-20KHZ 0-10V(newly increased) It can respective output square wave, triangular wave, sine wave. Digital frequency meter and DC voltmeter( it has A9, doesn’t has A6) Discrete component circuit Rectification, smoothing and voltage regulator circuit. Single stage amplifies circuit Two level rc-coupled amplification circuit Negative feedback amplifier circuit Emitter follower Differential Amplifier Complementary symmetry power magnifying circuit Potentiometer group Resistance, capacitance and Diodes Transistor, field-effect tube, silicon controlled, etc. 6. Integrated analog circuit Two independent operational amplifier (741), integrated power amplifier(LM386) Operator can configurate the board expansion areas according to requirement Main characteristic The experiment board front side of this experiment box adapt imported wrinkle varnish, with principle diagram and symbols. It is equipped with corresponding component, it can make the student increase the perceptual knowledge, the portion installed on locking connector which need measuring and observation, easy to operation, reliable, maintenance-free, simple and direct. Experiment circuit adapt unit circuit type design, each unit circuit based on the basic circuit, then connect to different component as circuit parameter, or according to different unit circuit combination, it can complete different experiment requirement. This experiment box is made up by integrated aluminium alloy profile, elegant colour and modelling, box fastness and reliable, no deformation, light weight, good insulation and safety performance, easy to open and close the case cover, nice exterior. 3 Experiment project 1)Single stage amplifies circuit 2)Two-level amplifier circuits 3)negative feedback amplifier circuit 4)emitter follower 5)Differential Amplifier 6) Proportional summational operation circuit 7)Integral and differential circuit 8)Wave generation circuit 9)Active power filter 10)Voltage comparator 11)IC circuit RC sine-wave oscillator 12)Integrated power amplifier 13)Rectifier filter and shunt regulating circuit 14)Serial regulating circuit 15)Integrated voltage stabilizer 16)RC sine-wave oscillator 17)LC oscillator and frequency-selective amplifier 18)Current /voltage switching circuit 19)Voltage / frequency switching circuit 20)Complementary symmetry power amplifier 21) Waveform inverter circuit 22)field-effect tube experiment (newly increased) 23)Silicon controlled experiment circuit ( newly increased ) Configuration: one experiment box mainframe One three core power line One experiment guidbook 35 double-end experiment line
