Basic Idea:

• Become familiar with the basic operation of an oscilloscope, and use it for voltage measurements.

What:	How Many:	Where:

Computers Needed?

• No.

• Location of equipment in lab:

  

  ---

• Audio Oscillator (hp model shown; others are similar):

  

  ---

• 1.1μF Decade Condenser box (attach a red and black spade lug, as shown):

  

  ---

• Decade Resistor box (attach a red and black spade lug, as shown):

  

  ---

• The Tektronix 2205 oscilloscope. Connect the BNC to double–banana adapters to CH 1 and CH 2 inputs (#15 in the photo below):

  

  ---

• Two Tenma signal generators are used (make sure the power supply in the back room is turned off, and configured properly for this type of connection!!):
  • Sine wave: Connect the GND terminal of the double-banana adapter to the green connector on lab bench; connect other terminal to red connector. Press the Sine curve & 10 buttons, and set the generator to 5 Hz.
  • Sawtooth wave: Connect to black connector on lab bench (don't use the GND connnector!). Press the Sawtooth & 100 buttons, and set generator to 100 or 200 Hz (display will read '001' or '002'). Pull out the duty switch to invert the signal to the correct orientation.
