Electronic Design

Group Assignment

Use the test equipment in your lab to observe the operation of a microcontroller circuit board.

At the NIHERST Fablab we had access to:

Regulated power supply

A regulated power supply provides a constant output voltage, independent of the output current. A regulated power supply with multiple regulators can offer multiple output voltages for operating different devices.

BK Precision 1760 A

  1. Output Voltage: 0-30V (2), 4-6.5V (1)
  2. Output Current: 0-2A (2), 5A (1)
  3. Input Voltage: 108-132VAC, 60 Hz
  4. Dimensions (WxHxD): 10.5 in. x 5.7 in. x 15 in.
  5. Constant voltage/Constant current mode
  6. Coarse and fine voltage controls
  7. Overload and reverse polarity protection

Digital multimeter

A digital multimeter is a test tool used to measure two or more electrical values—principally voltage (volts), current (amps) and resistance (ohms). It is a standard diagnostic tool for technicians in the electrical/electronic industries.

Fluke 179

  1. Voltage DC: max 1000V AC: max 1000V
  2. Current DC: max 10 A AC: max 10 A
  3. Resistance : max 50 MΩ
  4. Capacitance: 10,000 μF
  5. Temperature Range: -40 to 752°F (-40 to 400°C)

Oscilloscope

An oscilloscope is a device that allows you to see how voltage changes over time by displaying a waveform of electronic signals.

Tektronic TDS 2002

  1. Bandwidth: 60 MHz
  2. Analog Channels: 2
  3. Max Sample Rate: 1 GS/s
  4. Max Memory Depth: 0.0025 Mpts
  5. Operating System: Windows
  6. Form Factor: Benchtop

Signal Generator

A signal generator is one of the most essential pieces of technology in electronics and communication. It is used to produce di􀀂erent types of signals and frequencies for a variety of purposes such as testing, troubleshooting, and designing.

BK Precision 4017A

  1. 0.1 Hz to 10 MHz
  2. Sine, Square, Triangle, Pulse, & Ramp
  3. Coarse and Fine tuning
  4. 5 digit LED display
  5. Linear and log sweep
  6. Variable duty cycle
  7. Variable DC offset

Multimeter Testing

For this test we used one of the guys ATTiny 412 development board.
