Down Sequence
Connect the logic analyzer cables to the preprocessor interface as
shown in table 1-1. Descriptions such as J1 refer to connectors on the
preprocessor interface, while Pod 1 refers to a logic analyzer pod.
Figure 1-3 shows the relative locations of the logic analyzer cards.
HP 16542A with three or four Expansion Cards
The locations for the HP 16542A expansion cards, relative to the
Master Card, depend on the number of expansion cards used.
If
one
or two expansion cards are used, Card 1 is located above the Master
Card and Card 2 is located below the Master Card.
If
three expansion
cards are used, two of them are located above the Master Card and the
third is located below the Master Card. When four expansion cards
are used, they are located as shown in figure 1-3.
Table 1-1 shows the physical locations and connections for a
two-expansion-card system.
If
you are using more than two expansion
cards, check the Format menu in the logic analyzer to see where the
pods should be connected.
When powering up, the logic analyzer must be powered up first, and
then the target system. The logic analyzer provides the power to the
active circuits on the preprocessor interface; unpowered circuits may
cause improper operation of the target system.
When powering down, the target system should be powered down first,
and then the logic analyzer.
