Merged Modules
A merged module set consists of a master module and one or two slave modules
connected together by a merge cable connector, and by signals on the local bus
of the mainframe backplane. The local bus sends the system clock of the master
module to the slave modules. Refer to the
Tektronix Logic Analyzer Family User
Manual
for detailed merging instructions.
Merging Rules
The following LA module merging rules must be followed:
H
Only modules with 102 channels or more can be merged.
H
The modules must be physically adjacent, and physically connected.
H
Modules of unequal clock rate cannot be merged. All maximum sync rates
must match for the entire merged set.
H
Merged modules of unequal memory depths will assume the depth of the
shallowest module.
H
When merging two modules of unequal channel widths, use the module with
the higher number of channels as the master module.
H
When merging three modules of unequal channel widths, use the module
with the higher number of channels as the master module and use the module
with the fewest channels as slave two. Refer to
Three Way Merge on page
2--12 for details.
H
The modules should have the same firmware version.
H
Two or three TLA7Nx, TLA7Px or TLA7Qx LA modules may be merged
together. Two TLA7Lx and TLA7Mx LA modules may be merged together.
TLA7Nx, TLA7Px, or TLA7Qx LA modules may not be merged with
TLA7Lx and TLA7Mx LA modules. (Even if they are connected together.)
H
Merging operations may not be destructive to an established merged module
set. To merge a module to an established merged set, the established merged
set must first be unmerged through software. Unmerged modules are the only
potential candidates to add to a merged configuration.
