h. Check remaining vertical scale settings against limits (optional):
H
If desired, finish checking the remaining vertical scale settings for
the channel under test by repeating substeps d through g for each of
the remaining scale settings listed in Table 1–4 for the channel under
test.
H
When doing substep e, skip the subparts that turn on the CHx Pk-Pk
measurement until you check a new channel.
H
Install/remove attenuators between the generator leveling head and
the channel input as needed to obtain the six division reference
signals listed in the table.
i. Test all channels: Repeat substeps a through g for all four channels.
3. Disconnect the hookup: Disconnect the test hook up from the input
connector of the channel last tested.
