Testing Performance
To test the threshold accuracy (logic analyzer)
Test the
+
User threshold
1 Move the cursor to the field to the right of Pod AI. Type +6.00, then use the left and
right cursor control keys to highlight V. Press the Select key.
2 On the function generator front panel, enter +6.282 V ±I 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.
3 Using the Modify down arrow on the function generator, decrease offset voltage in
I-mV increments until all activity indicators for pod I show the channels at a logic
low. Record the function generator voltage in the performance test record.
