Test the ECL threshold
11 Select the field to the right of Pod 1, then select ECL in the pop-up menu.
22 On the function generator front panel, enter − 1.160 V ± 1 mV DC offset. Use the
multimeter to verify the voltage.
The activity indicators for pod 1 should show all data channels and the J-clock channel at a
logic high.
33
Using the Modify down arrow on the function generator, decrease offset voltage in
1-mV increments until all activity indicators for pod 1 show the channels are at a
logic low. Record the function generator voltage in the performance test record.
44 Using the Modify up arrow on the function generator, increase offset voltage in
1-mV increments until all activity indicators for pod 1 show the channels are at a
logic high. Record the function generator voltage in the performance test record.
