e. Measure the test signal: Press Close. Read the measurement results at the
Mean measurement readout. Refer to the following figure.
Figure 19: Measurement of offset accuracy
f. Check against limits:
■
CHECK that the readout for the measurement Mean readout on
screen is within the limits listed for the current vertical scale and
position/offset/generator settings. Enter the value on the test record.
■
Repeat substep 2.d, using the offset and generator settings as is listed
in the table.
■
CHECK that the Mean measurement readout on screen is within the
limits listed for the current vertical scale setting and position/offset/
generator settings. Enter the value on the test record.
■
Repeat substep 2.d, using the negative-polarity offset and generator
settings as is listed in the table.
■
CHECK that the Mean measurement readout on screen is within the
limits listed for the current vertical scale setting and position/offset/
generator settings. Enter the value on the test record.
■
Repeat substeps 2.c through 2.f until all vertical scale settings, are
checked for the channel under test. (See Table 11: Offset accuracy.)
g. Test all channels: Repeat substeps 2.a through 2.f for all four channels.
3. Disconnect the hookup:
a. Set the generator output to 0 V.
b. Disconnect the generator from the channel last tested.
