Connect the alligator clips of the Channel B voltage sensor to the wires at both ends of the 1 k
resistor.

Connect banana plug patch cords from the output of the Power Amplifier to the banana jacks on
the AC/DC Electronics Lab Board.

Part III: Data Recording - Diode and 1 k Resistor

Turn on the power switch on the back of the power amplifier.

Click the “ON” button (

) in the Signal Generator window.

Click the “REC” button (

) to begin data recording.

Data recording will end automatically after 250 samples are measured. Run #1 will appear in the
Data list in the Experiment Setup window.

Click the “OFF” button (

) in the Signal Generator window. Turn off the switch on the back

of the power amplifier.

ANALYZING THE DATA: Diode and 1 k

Resistor

Click the “Autoscale” button (

) to resize the Graph to fit the data.

The vertical axis shows Current in milliamps based on a calculation using the voltage drop across
the 1 k

resistor. The horizontal axis shows Voltage across the diode.

Select “Save As…” from the File menu to save your data. Select “Print Active Display” from the
File menu to print the Graph.

Click the “Magnifier” button (

). The cursor changes to a magnifying glass shape.
