Chapter 3: Testing Logic Analyzer Performance

Set Up the Test Equipment

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.

2 Set up the pulse generator according to the following table.

a Set the frequency of the pulse generator. In this test 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).

b Set the rest of the pulse generator parameters to the values shown in

the following table.
