Week 7 : Electronics Design

This weeks group assignment is to use the test equipment in the lab to observe the operation of a microcontroller circuit board.

1) Fluke 101 multimeter

The Multimeter in our lab is a Fluke 101. It is a very handy and strong tool to carry around. It can be used for some simple operations like:
- To find the AC and DC voltages. it can also read milli-volts.
- To find the continuity of the circuit.
- To test LED.
- To find the resistance value.
- To find the capacitance.
- To find the frequency.

For the group assignment we used the multimeter to check the continuity of the circuit.

2) Instek GPD-3303D

The Instek GPD-3303D 3-Channel Programmable Linear DC Power Supply, 195W, 100mV/10mA .

Tracking Series and Parallel Function

Tracking series and parallel function allows you to use the GPD-3303D in a wide range of applications. The tracking series mode guarantees higher output voltage, while the tracking parallel mode guarantees higher output current.

Convenience Functions

The GPD3303D knobs are digitally controlled, allowing for fine or coarse volume settings. The key lock feature locks panel operations, preventing accidental settings changes, which might damage the equipment.

4 Sets of Save/Recall

The GPD-3303D can save and recall panel settings; quickly select a panel setting from the four memory sets without the need for manual configuration.

USB Remote Control

The USB device port in the GPD3303D allows you to remotely control the power supply according to your application needs.

For the group assignment we used the Instek GPD-3303D for supplying sufficient DC current and voltage to the circuit.

3) AFG-2100/2000 Series Arbitrary Function Generator

The AFG-2100/2000 Series Arbitrary Function Generator is a DDS (Direct Digital Synthesized) based signal generato.It can generate output of Sine, Square (Pulse), Ramp (Triangle), Noise and Arbitrary waveforms. It provides 20M Sa/s sampling rate, 10 bit vertical resolution and 4k point memory .Also it can generate 0.1Hz resolution of Sine, Square and Triangle waveforms and the 1% ~ 99% adjustable duty cycle of Square (Pulse) waveform

For the group assignment, we used the AFG-2100/2000 for producing a certain signal wave and we varied the frequency and aplitude and checked it using a oscilloscope.

4) UniSource DS-1100 100 MHz, 2 Ch, Digital Storage Oscilloscope

When we are dealing with timing and signal shapes a simple multimeter became insufficent. We need to have something more to visualize and compare the signal. A digital storage oscilloscope is an apt choise for this.The DSO in our lap has the following capabilities.

- 100 MHz bandwidth, 1 M Memory
- High resolution color LCD display
- USB storage, RS232C & J45 interface
- 4000 point record length for each channel
- Multi-waveforms math, FFT Function
- Built-in delay sweep function
- Automatic Multi-waveform Measurement
- Cursor & Track measurement
- Waveform Record & Recall, Trigger Mode for Edge, Video, Pulse Width, Slope & Alternate
- Display of date, clock and help information
- Also available in 60 MHz DS-1065, 100 MHz DS-1200

For the group assignment, we checked our programmed micro-controller with the oscilloscope.
