cation procedure

Complete the following steps to complete this procedure. Record the results
on the Calibration Data Sheet.

1.

Set the DTG sequencer to RUN and the outputs ON.

2.

Press the RUN button on the TLA and wait a few seconds to verify that it
does not trigger.

3.

Starting from 0.000 ns, increase the delay of the DTG clock channel in 100 ps
steps until triggering begins to occur. When the TLA begins to trigger,
decrease the delay in 10 ps steps to

fi

nd the trigger threshold to within 10 ps.

Record this delay amount.

Note that the logic analyzer might trigger because of a glitch when you make
a delay change. If the data in the waveform window is correct (all data
transitioning at the same time and at the correct frequency), then ignore this
"false trigger" and start the logic analyzer again.

As an alternative, you may want to run the logic analyzer in continuous loop
mode if the DTG causes a false trigger on the logic analyzer each time you
change the delay. Then observe if the data is correct in the waveform window
and ignore any false triggers. Continue increasing the clock delay until the
waveform window displays data that was not acquired correctly. Record this
delay.

4.

Add 300 ps to the delay value that you recorded in step 3 and increase the
DTG clock delay to match this cumulative value. (For example, if you
measured 600 ps, increase the delay to 900 ps.)

5.

Press Run and wait a few seconds to verify that it does not trigger. This
veri

fi

es that the setup and hold window is less than 300 ps, which is the

guaranteed speci

fi

cation for a single channel.

To measure the actual setup and hold window size for your application, slowly
decrease the clock delay in steps (waiting a few seconds between steps to
verify that it does not trigger), until the logic analyzer triggers. Record this
second value. The difference between this second value and the value that you
measured in step 3 is the measured setup and hold window size.
