Test the complement of the bits
Now test the logic analyzer using inverted levels (in other
words, complement data).
1 On the pulse generator, in the PULSE setup for CHANNEL
2, select inverted levels:
On the 81134A pulse generator, select Levels: Inverted.
•
On the 8133A pulse generator, select COMP (LED on).
•
Verify the DC offset and adjust it if necessary. See
2
page 37.
3 Adjust the sampling positions (run Eye Finder). See
page 46.
Determine pass or fail (1 of 2 tests). See
4
Switch to the Listing window by selecting the Listing tab
5
at the bottom of the main logic analyzer window.
6 Select the Run Repetitive icon
7 Determine pass or fail (2 of 2 tests). See
1 Disconnect the E5382A Flying Lead Probe Set from Pod 1
and connect it to Pod 2 of the logic analyzer. (The clock
input on Pod 3 remains the clock input when testing
Pod 2.)
On the pulse generator, in the PULSE setup for CHANNEL
2
2, return the outputs to normal (non- inverted or
non- complement) levels.
3 Verify the DC offset and adjust it if necessary. See
page 37.
In the Overview window, select SetupBus/Signal... from
4
the module's drop- down menu.
5 Scroll to the right and unassign all Pod 1 bits.
6 Set the Pod 2 threshold to 500 mV (just as you did for
Pod 1 on page 43).
Assign bits 2, 6, 10, and 14 of Pod 2.
