READY Indicator.
The READY indicator lights continuously after the logic
analyzer module successfully completes the power-on process. If the indicator
fails to light within five seconds of power-on, an internal module failure may be
present.
ACCESSED Indicator.
The ACCESSED indicator lights anytime the controller
accesses the logic analyzer module.
ARM’D Indicator.
The ARM’D indicator lights when the logic analyzer module is
armed during an acquisition.
TRIG’D Indicator.
The TRIG’D indicator lights when the logic analyzer module
triggers and stays on until the module finishes acquiring data.
The merge cable connectors (not shown) are located on the sides of the logic
analyzer module. The connectors are used to merge up to three logic analyzer
modules together to create a two- or three-wide logic analyzer module.
Two Merged Modules. When two modules are merged, the master module is on
the left (lower numbered slot) and the slave module is on the right.
Three Merged Modules.
When three modules are merged, the master module is in
the center, and the slave modules are on the right and left of the master module.
Merge Cable Connector.
The merge cable connector is located on the side panel of
the module. When the module is used by itself the merge cable is stored inside
the cover.
When you merge modules together, you must set up the merge connector so that
it mates with an adjacent logic analyzer module. Instructions for merging
modules are described in the
Tektronix Logic Analyzer Family User Manual
.
Four rear panel connectors (see Figure 2--1 on page 2--2) connect the logic
analyzer module to the backplane of the mainframe. The module receives power,
processor communication, and intermodule communication through these four
connectors.
Logical Address Switches.
Figure 2--1 on page 2--2 shows the location of the
logical address switches.
