4. Set the input voltage on the DC source to approximately 1.4 V. Record the actual voltage as V
in
1.
5. Record the output voltage as V
out
1.
6. Reverse the polarity of the input voltage on the DC source. (Swap the MicroCKT test tips or the Y-lead adapter.)
Record the actual voltage as V

7. Record the output voltage as V

8. Calculate the attenuation using the values from the measurements as follows:
Attenuation = (V
in
1 - V
in
2) ÷ (V
out
1 - V
out
2)
Example:
= [1.4 V – (–1.4 V)] ÷ [0.28 V – (–0.28 V)]
= 2.8 V ÷ 0.56 V
= 5.0
9. Verify that the attenuation is in the range of 4.9 to 5.1. Record the results in the test record.
Leave the probe connected for the next test.
