Part 3-Check Bandwidth
Procedure
Perform this procedure for each Vertical Size listed in Table 2-2; then repeat for CH
2 .
This procedure may require the use of
than one Leveled Sine Wave Generator
to test all the frequencies listed in Table 2-2.
If the Leveled Sine Wave Generator is not equipped with internal attenuators, then
use two
at the plug-in unit input when setting amplitude.
To
the amplitude, either count the divisions,
the AV cursors, or use the
peak-to-peak measurement
function (11400
series mainframes only).
a.
Set the Leveled Sine Wave Generator amplitude as shown in the Reference
Amplitude columns.
b . Set the Leveled Sine Wave Generator frequency as shown in the Frequency
column (according the mainframe type you are using).
c.
the displayed amplitude is at least the value shown in the
CHECK Amplitude column.
d .
Set the Leveled Sine Wave Generator to the Reference frequency.
Set Vertical Size as shown in the next line of Table 2-2.
