The device composed mainly of two parts, part experiment, the number of functional plate, the other part for the experimental model, functional board, composed of the following major functions:
Several experimental functional electrical plate:
DC Power Supply: ± 5V, 1A two road; 0.0 to 18 V, 0.75A consecutive adjustable two-way (through the appropriate connections, can be 0 to ± 18V and 0 to 36 V continuous adjustable power supply), +5 V power supply also a short-circuit the police, instructions function, both short-circuit power over soft deadline for automatic restoration of protection.
Pulsed Signal Source: Counting pulse source 0.5 HZ ~ 300KHZ continuously tunable output four-way BCD code-frequency, the frequency, the frequency quarter, eight frequency or baseband output frequency at 1 HZ, 1KHZ, 20KHZ; 3 rough emphasize that every stalls can be carried out to fine-tune the vicinity; plus or minus two single-output pulsed source of the two roads.

Four groups are allocated codes set, reset button, speakers, music sheets and potential vehicles.
Built with high reliability integrated block round pin sockets (40 P2 only, 28 P1 only, 24 P1 only, 20 P1 only, 18 P1 only, 16 P5 only, 14 P5 only, 8 P1 only) and silvering of Red Copper Pipe, and integrated block for the various devices inserted and so on.
Components board (optional): - can be inserted in a few functional board test experimental components will be used in cable access circuit. If not qualified components boards, devices can also be directly inserted Red Copper Pipe silvering long experiment.
Die plate, experimental features:
DC Power Supply: ± 5V, 1A two routes, 0.0 to 18 V adjustable two consecutive road (through the appropriate connections, available 0 ~ ± 18V and 0 to 36 V continuous adjustable power supply), +5 V power supply also has shorted Alarm directing function, each power are soft deadline for automatic restoration of short circuit protection function.
DC signal source: - 5V ~ +5 V adjustable two consecutive road.
AC power: 0V, 6V, 8V, 10V, 14V, 16V tap power all the way, the center tap 7 V power supply from two directions, the center tap 17 V power supply from two directions, each power uniform have short-circuit protection automatically restore function. Control screen left and right with 220 V single-phase three-socket several months.
Signal Source: output sine, triangle wave, square wave, frequency of 15 Hz ~ 90KHZ continuously tunable. Range 0 to 10 VPP continuously tunable.
Six figures significantly Cymometer: 1HZ ~ 300KHZ.
DC Digital Voltmeter: sub 2 Mv, 2V, 20V, 200V 4th speed, straight bond switch handoff, three half significantly, 0.5 precision, the input impedance 10 megohms.
DC figures milliamperes table: at 2 mA, 20mA, 200mA; 3, the switch handoff straight bond, triple-digit significant, 0.5 accuracy.
With 1 mA 100 ohm internal resistance DC milliamperes Pointer table, relays, pulse transformers and output transformers, speakers, buzzer, oscillating coil, SCR, 12 V lights, power resistors, Bridge heap, diodes, integrated regulator block , capacitor, transistor, such as buttons and Potentiometers.
All fixed-line direct experimental module to module, experimental design board.
Specific fixed-line experiments are:
① total emitter transistor single-tube amplifier
② negative-feedback amplifier
③ emitter follower
④ sine wave oscillator
⑤ differential amplifier
⑥ power amplifier
⑦ single tube amplifier with negative feedback amplifier comprising 2
⑧ single tube, negative feedback and follow-emitter amplifier comprising three poles
Experimental over fixed lines, it is not necessary, to enable students to complete ensembles of experimental circuits experiment.
Components board (optional): Mold can be planted on the board, experimental features, experimental components will be used in cable access circuit. If not qualified components boards, devices can also be directly inserted Red Copper Pipe silvering long experiment.
