6. Event Based Selections Depending on the trigger event you choose other selections may become available Refer to the online help for further informa tion The system trigger is a global trigger event that forces all untriggered modules to arm immediately and trigger Only one system trigger occurs per acquisition When displaying data the logic analyzer uses the system trigger as the primary reference point for the acquisition The data windows show the system trigger and all module triggers Module triggers can be forced by the system trigger or specified by module trigger programs The system trigger can be generated from any of several sources Often the system trigger is specified in a module s trigger program Any module can specify the system trigger as a trigger action Trigger All Modules However modules can specify trigger actions other than system triggers and the system trigger does not have to originate from a module The logic analyzer can also accept a system trigger generated by an external source External system triggers are input through the SYSTEM TRIG IN connector Regardless of the source of the system trigger all modules must respond It is not uncommon to have a condition where the acquisition completed but where an explicit system trigger did not occur This means that there was neither an external system trigger nor a system trigger generated internally by a module trigger program To ensure that a ti

Glitch violation storage The acquisition memory can be enabled to store glitch violation information with each data sample when asynchronous clocking is used The probe data storage size is reduced by one half the other half holds the violation information The fastest asynchronous clocking rate is reduced to 10 ns 1 For merged modules the master module is the module installed in the lower numbered slot 2 Each use of a glitch detector setup and hold violation detector or transition detector requires a trade off of one word recognizer resource 3 Any glitch is subject to pulse width variation of up to the channel to channel skew specification 0 5 ns 4 Any setup value is subject to variation of up to 1 6 ns any hold value is subject to variation of up to 1 4 ns 5 This mode can be used to create transitional storage selections where all channels are enabled Counters and timers can be set reset or tested and have zero reset latency Timers can be tested with TLA 7Lx and TLA 7Mx Modules with serial numbers B020000 and higher and TLA 700 Series Software Version 1 10 and higher Word recognizers are traded off one by one as Signal In 1 Signal In 2 glitch detection setup and hold detection or transition detection resources are added Block storage is disallowed when glitch storage or setup and hold violation is enabled TLA 700 Series Logic Analyzer User Manual Appendix A Specifications Table A 22 L

12. 2 2 TLA 700 Series Logic Analyzer User Manual Operating Basics The signal you chose as the external clock to the logic analyzer should be the same signal that controls the activity of the other signals you want to observe For example to observe the output states of a counter chip you might use the clock input to the counter chip to act as the external clock source to the logic analyzer With this setup each clock pulse to the counter chip could also be used to clock data from the counter s output lines into the logic analyzer As another example to record the data being written to a latch you could use the load signal to the latch as the external clock source to the logic analyzer Internal Asynchronous Clocking Much activity can occur in the target system between system clock signals Using the LA module s internal asynchronous clock you can view all activity in the target system not just the data available at the target system clock signal Internal clocking is the best choice when you are primarily interested in the timing aspects of the data Internal clocking is a natural choice for waveform timing analysis It is important to note however that the value of internal clocking is not limited to just displaying waveforms For a detailed picture of data activity both during and between state changes use internal clocking For example when you use internal clocking you are able to acquire and display glitch information
