Pod Threshold Field
Use the Pod Threshold field to set a voltage level the data must reach before
the analyzer recognizes and displays it as a change in logic levels. You specify
a threshold level for each pod. The level specified for each pod is also
assigned to the pod’s clock threshold. When the Pod Threshold field is
touched, a threshold selection pop-up menu appears with the following
choices:
TTL
When TTL is selected as the threshold level, the data signals must reach +1.5
volts.
ECL
When ECL is selected as the threshold level, the data signals must reach –1.3
volts.
USER
When USER is selected as the threshold level, the data signals must reach a
user selectable value between –6.0 volts to +6.0 volts.
