Table 1- 7: Merged modules
Characteristic Description
Number of merged modules 2, 3, 4, or 5 adjacent modules can be merged. Only 102-channel modules or
136-channel modules can be merged. Merged modules can have unequal channel
widths and channel depths.
See Figure 1--1 for location of modules in a merged configuration.
Number of channels after merging The sum of all channels available on each of the merged modules including clocks
and qualifiers. No channels are lost when modules are merged.
Merged system acquisition depth Channel depth is equal to that of the shallowest module.
Number of clock and qualifier channels after
merging The qualifier channels on the slave modules can only be used as data channels. They
cannot influence the actual clocking function of the logic analyzer (for example, log
strobe generation).
The clock channels on the slave TLA7Axx modules can capture data on those
modules for source-synchronous applications. Each slave module contributes four
additional clock channels to the merged set. All clock and qualifier channels are
stored to acquisition memory.
Merged system trigger resources The same as a single module except for word recognizer width, setup and hold
violation detector width, glitch detector width, and transition detector width has
increased to equal that of the merged channel width. Range recognizers will increase
to the merged channel width up to three modules; range recognition is not supported
on the two outside slave modules.
