Chapter 3: Testing Logic Analyzer Performance
Test Pod 2 in 500 Mb/s Mode
SMA/Flying Lead test connector's pin strip connector at the 8133A pulse
generator's Channel 2 OUTPUT.
4 Connect the Pod 2 E5383A Flying Lead Probe Set's bits 2 and 10 to the
SMA/Flying Lead test connector's pin strip connector at the 8133A pulse
generator's Channel 2 OUTPUT.
5 On the 8133A pulse generator, in the PULSE setup for CHANNEL 2, press
the COMP button to return the outputs to normal.
6 Note that the signal on the oscilloscope has moved. Change the
oscilloscope's horizontal position to 525 ps (or as required) to center the
measured pulse on the oscilloscope display.
7 Verify the DC offset and adjust it if necessary. See page 36.
8 Deskew the oscilloscope if necessary. See page 37.
9 Readjust the pulse width from the pulse generator as measured on the
oscilloscope. See page 39.
10 Unassign all Pod 1 bits.
11 Assign bits 2, 6, 10, and 14 of Pod 2.
12 Ensure that the Pod 2 threshold is set to 1 volt (just as you did for Pod 1
on page 41).
13 Adjust the sampling positions using Eye Finder. Be sure to expand "My
Bus 1", align the blue bars vertically, and use the starting position you
noted on page 55. Realign any stray channels if necessary. See page 46.
14 Determine pass or fail (1 of 2 tests). See page 47.
15 Switch to the Listing window.
16 Select the Run Repetitive icon
17 Determine pass or fail (2 of 2 tests). See page 49.
Test the complement of the bits (Pod 2, 500 Mb/s mode)
1 Test the complement of the bits on Pod 2. You can use the procedure "Test
the complement of the bits (250 Mb/s mode)" on page 50 as a guideline.
