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 Select Setup > Acquisition.

Notes:

• Where the BNC Tee adapter is used, it is important to connect it directly to the scope channel input

using the BNC (f) to SMA (m) adapter and the connection saver 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.

• 256 averages are used in the scope measurements of this section to reduce measurement noise and to

reduce the measurement error due to resolution.
