Test equipment setup
Connect a P5910 probe from the logic analyzer to the voltage source, using the
Threshold Accuracy test
fi
xture. If the voltage source does not have the required
output accuracy, use a multimeter with the required accuracy to verify the voltage
output levels speci
fi
ed in the procedure.
TLA6400 setup
To set up the logic analyzer for this test, you must de
fi
ne the characteristics of the
channel that you are testing, and then set the trigger parameters:
1.
Open the Setup window.

In the Group column, enter a name for the probe group that you are testing
(“Test” in the example).
b.
De
fi
ne the signals for the group that you are testing.
c.
Set the sampling to Asynchronous, 2.0 ns.
d.
Set the Acquisition Length to 128K or less.
e.
Set Acquire to Samples.
2.
Go to the Trigger window and select the Power Trigger tab. Create a trigger
program that triggers the logic analyzer when it does not see all highs or
all lows:
a.
Click the If Then button.
