16800 Series Portable Logic Analyzers Service Guide
1 Turn on the required test equipment. Let all of the test
equipment and the logic analyzer warm up for 30 minutes
before beginning any test.
Set up the pulse generator according to the following
2
table.
Set the frequency of the pulse generator. In this test
a
procedure, the logic analyzer uses both edges of the
clock to acquire data. The test frequency is half the
test clock rate because data is acquired on both the
rising edge and the falling edge of the clock. Set the
frequency to 125 MHz plus the frequency uncertainty
of the pulse generator, plus a test margin of 1%.
For example, if you are using an 8133A pulse
generator, the frequency accuracy is ±1% of setting. Use
a test margin of 1%. Set the frequency to 125 MHz plus
2% (127.5 MHz).
Set the rest of the pulse generator parameters to the
b
values shown in the following table.
