Trigger Setup

Trigger Setup is used to define a set of trigger conditions. The LAP-F1 will trigger on

the first event that satisfies all the conditions; see the dialog box in Figure 4-25.

Figure 4-25 Trigger Setup dialog box

Item

Description

Group 0 (Port A/B)

and

Group 1 (Port C/D)

The first 16 channels are sampled by ports A0-15 (Group A), the

next 16 in ports B0-15 (Group B) etc. For the 40 channel LAP-F1

model all ports from channel C9 to D15 are disabled. For LAP-F1

trigger conditions can only be set for 32 channels at a time.

However; there exists an OR relationship between the Group 0 and

Group 1; this OR condition is automatically enabled if the user sets

trigger conditions in both of the groups.

Trigger Mode

Internal Trigger

Fulfillment of a condition set makes the LAP-F1 emit a trigger
