Test Pod 2 in 500 Mb/s mode

64
The logic analyzer master card's Pod 1 clock ("Clk1" in the
Sampling setup dialog) is used for testing all Pods above 1 in
the 500 Mb/s mode. Therefore, two E5383A Flying Lead
Probe Sets are required to test Pod 2 and the remaining
pods.
Disconnect the first E5383A Flying Lead Probe Set from
1
the pod it is currently connected to (Pod 1) and connect
it to the pod under test (Pod 2).
Remove the pod under test Flying Lead Probe Set's CLK
2
lead from the SMA/Flying Lead test connectors. (Do not
remove the channel 2, 6, 10, and 14 leads from the
SMA/Flying Lead test connectors.)
Connect a second E5383A Flying Lead Probe Set to Pod 1
3
of the logic analyzer's master card.
4 Connect the Pod 1 Flying Lead Probe Set's CLK lead to
the SMA/Flying Lead test connector's pin strip connector
at the 8133A pulse generator's Channel 1 OUTPUT.
On the 8133A pulse generator, in the PULSE setup for
1
CHANNEL 2, press the COMP button to return the
outputs to normal.
Note that the signal on the oscilloscope has moved.
2
Change the oscilloscope's horizontal position to 525 ps (or
as required) to center the measured pulse on the
oscilloscope display.
3 Verify the DC offset and adjust it if necessary. See
page 41.
Deskew the oscilloscope if necessary. See
4
Readjust the pulse width from the pulse generator as
5
measured on the oscilloscope. See
6 Unassign all Pod 1 bits.
7 Assign bits 2, 6, 10, and 14 of Pod 2.
Ensure that the Pod 2 threshold is set to 1 volt (just as
8
you did for Pod 1 on
page
page 46).
