Chapter 3: Testing Performance
DC Gain Accuracy Test

Procedure
1
Make the connections to scope channel 1 as shown below.
Connections
2
Press Default Setup, then configure the scope as follows:
a Pull down the Setup menu and select Acquisition.
Notes:
• Where it is used, it is important to connect the BNC Tee adapter directly to the scope channel input
to minimize ground potential differences and to ensure that the DMM measures the input voltage to
the scope 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 scope and DMM are connected to the same
AC supply circuit.
• A fairly large number of averages are used in the scope measurements of this section to reduce
measurement noise and to reduce the measurement error due to resolution.
