e. Measure the test signal: Press the Close button.
■
Read the measurement results at the measurement statistics Mean
measurement readout. Refer to the following figure.
■
Record the Mean in the Measurement Mean column. (See Table 9:
Gain accuracy on page 213.)
Figure 15: Measurement of DC gain accuracy
f. Measure second mean:
■
Set the generator to the second level and polarity indicated in the
table for the vertical scale, position, and offset settings you have
made.
■
Repeat substep 2.e using the current vertical scale, position, offset,
and new generator setting for the second mean.
g. Check against limits:
■
Subtract the second measurement mean from the first measurement
mean for the current vertical scale, position, and offset.
■
Record the difference of the two mean measurements in the
Difference of Measurement Means column of the table. (See Table 9:
Gain accuracy on page 213.)
■
CHECK that the Difference of Measurement Mean is within the
limits listed for the current vertical scale/position/offset/generator
settings. Enter measurement mean difference value on test record.
h. Repeat substeps 2.d through 2.g, using the next position, offset and
generator settings listed in the table for the current vertical scale.
