With the rapid introduction of ICs in modern electronics a good understanding of digital and linear ICs are considered necessary, as these ICs constitute the alphabet of computers and instrumentation. Evaluating the designed circuit for its intended performance is an important criterion. In order to facilitate the above requirement, the Electronic Design Experimenter is designed. This instrument has facilities to conduct the same. The circuit components often constitute resistors, capacitors, ICs etc. You can construct your circuit design on the breadboard provided with the instrument, without soldering.

Specifications:

Mode Switch: This is used to select output voltages of Pulse generator, Pulser switch, or Logic switches in the range of 0 to +8V DC.

Inputs:

Logic Switch Inputs – 6 Nos.

De-Bounced Pulser input – 1 No

Free running TTL clock generator in Two ranges

Outputs:

TTL Compatible Lamp indicators – 6 Nos.

Independent 7 segment displays with decoders – 2 Nos.

Solder less breadboard:

Solder less breadboard with more than 3,300 junction points are available to construct simple experiments. All transistors, ICs and components are plugged into the socket pins of the breadboard. Each socket pins is connected to four more sockets internally. Interconnections are made by hook up wires of 0.3mm to 0.8mm diameter. The breadboard accepts transistors, resistors, capacitors, ICs, etc. The leads should not be thicker than 22 SWG.

All terminals are spring loaded to connect upto 6 numbers using 22SWG single stranded hookup wire in the same terminal.

All spring terminals are plated and bright finished for better conductivity.

Pulse Generator: Continuously variable in the range of 1 Hz to 1 MHz in 7 positions.

Built-in Power supply:

It has one fixed 5V @ 1A regulated power supply.

- 5V fixed source @ 1A

Independent variable power source adjustable from +1.2V to +15V @ 500mA.

Independent variable power source adjustable from - 1.2V to –15V @ 500mA. For energizing NPN-PNP transistors & Op-amps etc.

Mains Power: The instrument can be directly plugged into 230V AC mains outlet.

Dimensions:

L= 400mm X B=310mm X = H 80mm

Weight: Approximately 5 Kgs.

This instrument is housed in an elegant, strong and sloping cabinet.

OPTIONAL ACCESSORY: The optional accessory is intended to connect the signals from an IBM computer through a dedicated ADD-ON card Model IBR-1. The patch panel consists of 97 spring loaded terminals (96 TTL I/O lines and One ground terminal) from which interface experiments can be conducted, Using single strand wires for interconnections. This panel is included along with ADD-Card.

This ADD-ON card is provided with necessary Dynamic Link Libraries (DLLs) on installation CD, to invoke the system, using VISUAL BASIC OR VISUAL C++ with all the GUI functions for learning better graphical programming functions. Programmable in High-Level languages like BASIC, TURBO PASCAL, C etc. Programmable even in language like MASM.

The functions of the ADD-ON card are

• Graphical Utility Interface (GUI) functions are supported, when software is installed.
• Necessary patch cord panel is supplied from which all the TTL lines from the IBM computer are accessible for interface function experiments.
• 96 TTL/DTL Digital I/O lines, using industry standard 8255 PPI
• No need to have buffers circuit of Address bus, Data bus or control bus, from computer to digital trainer or make decode circuitry for Input Output functions. Invoking Input output functions could directly access the system.
• Plugs into IBM PC/XT/AT Bus or compatibles.
• Unidirectional, bi-directional strobed I/O.
• Direct interface to wide range of peripherals.
• Programmable in High-Level languages like BASIC, TURBO PASCAL, C, VISUAL BASIC etc.
• Programmable even in language like Microsoft Assembler (MASM).
• All 8255s are connected through buffers to PC BUS.
• Jumper selectable I/O addresses.
