Part One (not in the lab manual)
Circuit Diagram for new experiment:
This diagram shows how the circuit should be wired up so we can measure the phase shift with the oscilloscope.
The coaxial cable connections are already made, as shown in the
pictures on the main page for this lab and below.
(Be sure to push in the button to select the sine function.)
This closeup of the photo used above shows the details of the settings on the oscilloscope. When you arrive, it will probably look like this picture, which shows a scope after it was used for the previous lab experiment. The blue arrows highlight features we need to pay attention to this week.
The function generator should have the sine button pushed in.
The three buttons along the buttom should all have been "out"
for the previous lab, but check that they are still correct.
Conversion from Part One to Part Two is fairly simple. We basically just replace the CH2 connection to the oscilloscope with the multimeter. There is no problem leaving the oscilloscope connected at CH1, so all you really need to do is to disconnect the leads from CH1 and connect them to the multimeter. Set the meter to read AC rms Volts, and then adjust the amplitude of the generator to its maximum value.
Follow the instructions in the lab manual from this point on.
The set of cables shown in the picture below contains the ones you
will have available for this lab. The set above
the meter stick includes a red-black pair of 100 cm leads and
a red-black pair of 65 cm leads. One of these pairs is usually
used to make connections to the multimeter while the other is
used to connect to the power supply.
