Analog/Digital Training System:

The Analog/Digital Training System consists of DC power supply, breadboard, pulse generator and a

digital probe.

Useful features include:

1. DC Power Supply:

 Fixed DC Outputs: +5V & -5V

 Variable DC Outputs: +3V to +15V, -3V to -15V

2. Breadboard:

 Terminal strips arranged for easy connection of standard ICs

3. Pulse Generator:

 Variable duty cycle: (set to 50%)

 Frequency range: 1Hz – 10MHz

 Amplitude: 0VP-P - 10 VP-P

4. Digital Probe

The Breadboard

The breadboard consists of two terminal strips and two bus strips (often broken in the centre). Each bus

strip has two rows of contacts. Each of the two rows of contacts is node. That is, each contact along a

row on a bus strip is connected together (inside the breadboard). Bus strips are used primarily for power

supply connections, but are also used for any node requiring a large number of connections.

In the example of breadboard shown in figure 1.1, each terminal strip has 60 rows and 5 columns of

contacts on each side of the centre gap. Each row of 5 contacts is a node.

You will build your circuits on the terminal strips by inserting the leads of circuit components into the

contact receptacles and making...
