Pod Threshold Field

Pod Threshold Field
The pod threshold field is used to set a voltage level which the data must
cross 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 the
master pod, which includes the clock, is also assigned to the clock.
TTL When TTL is selected as the threshold level, the data signals must
cross +1.5 volts.
ECL When ECL is selected as the threshold level, the data signals must
cross −1.3 volts.
USER When USER is selected as the threshold level, the data signals
must cross a user selectable value between −5.0 volts to +5.0 volts.
