Procedure
1
Make the connections to oscilloscope channel 1 as shown below.
NOTE
• Where the BNC Tee adapter is used, it is important to connect it directly to the oscilloscope
channel input using the BNC (f) to SMA (m) adapter and the connector saver to minimize
ground potential differences and to ensure that the DMM measures the input voltage to the
oscilloscope channel as accurately as possible. Differences in ground potential can be a
significant source of measurement error, particularly at high scope sensitivities.
• It also helps to reduce ground potential differences if the oscilloscope and DMM are
connected to the same AC supply circuit.
• 256 averages are used in the oscilloscope measurements of this section to reduce
measurement noise and to reduce the measurement error due to resolution.
