d. ≥ 4GHzmodels:Display the test signal:
Remove the attenuator.
Set the generator frequency to 10 MHz. S
et the Horizontal SCALE as
indicated in the table. (See Table 3-12.)
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 3-12.)
Set the generator frequency to the frequency in the table that
corresponds to the amplitude just set. Set the Horizontal SCALE as
indicated in the table. (See Table 3-12.)
Check that a stable trigger is obtained.
Read the following d
efinition: 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.
