Voltage or Threshold Level.
TTL Probe (for LAP-F1)
The LAP-F1 lets users use up to 4 different Trigger Levels at a time; one for each of
the four port A, B, C and D. For each port, three pre-defined levels are available:
1.2/1.5/1.8 IO voltages. It is also possible to user-define the Trigger Level. See the
dialog box in Figure 4-21.
