≥ 4 GHz models:
Display the test signal:
■
Remove the attenuator.
■
Set the generator frequency to 10 MHz. Set the Horizontal SCALE as
indicated in the table. (See
Table 18: Trigger settings for ≥ 4 GHz
■
Fine adjust the generator output until the
Ch 1 Amplitude
readout
indicates the amplitude listed in the table for a frequency not yet
checked. (See
Table 18: Trigger settings for ≥ 4 GHz models
page 263.)
■
Set the generator frequency to the frequency in the table that
corresponds to the amplitude just set. Set the Horizontal
SCALE
as
Table 18: Trigger settings for ≥ 4 GHz
■
CHECK that a stable trigger is obtained.
■
Read the following definition: A stable trigger is one where the
Trig'd
LED will remain constantly lighted.
■
Press the Trigger
Slope
button to select the positive slope.
■
Adjust the Trigger
Level
knob so that there is a stable trigger.
CHECK that the trigger is stable.
■
Press the Trigger
Slope
button to select the negative slope. Adjust the
Trigger
Level
knob so that there is a stable trigger.
■
CHECK that the trigger is stable.
■
Enter pass or fail in the test record.
