Setting the Pod Threshold

The pod threshold is a voltage level which the data must cross before
the analyzer recognizes it as a change in logic levels. You can specify a
threshold level for each pod. The level specified for the master pod that
includes the clock is also used for the clock threshold.
Standard
1. In the Format tab, select the threshold button located just below the pod
name.
2. In the Pod threshold dialog, choose one of the standard threshold options:
• TTL -- The threshold level is +1.50 volts.
• LVTTL -- The threshold level is +1.40 volts.
• SSTL2 -- The threshold level is +1.50 volts.
• SSTL3 -- The threshold level is +1.25 volts.
• LVCMOS 1.5v -- The threshold level is +0.75 volts.
• LVCMOS 1.8v -- The threshold level is +0.90 volts.
• LVCMOS 2.5v -- The threshold level is +1.25 volts.
• LVCMOS 3.3v -- The threshold level is +1.65 volts.
• CMOS 5.0v -- The threshold level is +2.50 volts.
• ECL -- The threshold level is -1.3 volts.
• LVPECL -- The threshold level is 2.00 volts.
3. If you don't want the change to apply to all pods, deselect the checked box
next to Apply settings to all pods.
4. Select the Close button.
