Test Pod 2 in 200 Mb/s mode

1 Leave the first E5382A Flying Lead Probe Set connected to Pod 1 of the

logic analyzer. Remove the Pod 1 flying leads 2, 6, 10, and 14 from the

SMA/Flying Lead test connectors. Do not remove the flying leads that are

connected to CLK and CLK.

2 Connect the second E5382A Flying Lead Probe Set to Pod 2 of the logic

analyzer.

3 Connect the Pod 2 E5382A Flying Lead Probe Set’s bits 6 and 14 to the

SMA/Flying Lead test connector’s pin strip connector at the 8133A pulse

generator’s Channel 2 OUTPUT.

4 Connect the Pod 2 E5382A 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 800 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 46.

8 Deskew the oscilloscope if necessary. See page 47.

9 Readjust the pulse width from the pulse generator as measured on the

oscilloscope to 1.5 ns. See page 48.

10 In the logic analyzer’s Setup and Trigger window, Format tab, unassign all

pod 1 bits. A Warning window will appear stating that the trigger function

has become invalid. Select OK to close the Warning window.

11 Assign bits 2, 6, 10, and 14 of Pod 2.

12 Set the Pod 2 threshold to 1 volt (just as you did for Pod 1 on page 53).

13 In the “Setup and Trigger...” window, Format tab, use the scroll bar at the

bottom of the window to scroll to the left. Ensure that the J clock

threshold is set to Differential.

14 Re-establish the trigger function:

a In the logic analyzer’s Setup and Trigger window, select the Trigger tab,
