DESCRIPTION


The EB-3000 is a base unit packaged in a sturdy plastic case (36 x 26 cm) for accepting electronics and communications experiment plug-in cards.

The system uses an external switching power supply for safety reasons.


The power supply low voltage output is converted to the 5 voltages by linear regulators to reduce noise.

Two potentiometers on the panel are used to setup the variable voltage and the function generator amplitude. Two toggle switches select CMOS/TTL level and sine wave / triangle wave.

The system cuts-off the voltages for an overload and displays an appropriate error massage.

The plug-in cards are connected directly to system without any flat cable to reduce noise and resistance.

The system is controlled by a very powerful, internal controller.

The 10 relays have change-over contacts that can switch active and passive components.

Every selection of a relay configuration is saved in nonvolatile memory located on the connected plug-in card. This configuration feature does not require a PC.

The components are located on the board by the silk screen print of the actual circuit under test and component symbols.

The central part of the experimenting board includes all the circuit block drawings, all hands on components, test points and banana sockets.

The protected components are located on the plug-in circuit board upper side, clearly visible to the student and protected by a sturdy transparent cover that is permanently mounted on the EB-3000 platform.
