3. great number of events surrounding the trigger In some situations where it is difficult to pinpoint an exact event for triggering the breadth of a 512K data buffer can still capture the desired data Other logic analyzers with typical 1K to 8K buffers can easily miss capturing the desired data in this situation Not Only a Logic Analyzer It s a Powerful Pattern Generator A 100 Mbit s Pattern Generator option is available for the LA 52xx and LA 55xx Logic Analyzers As few as 8 channels or as many as 160 channels can be dedicated to Pattern Generator output while leave the remaining channels for simultaneous use as a Logic Analyzer Data for the Pattern Generator can loaded from a file edited by the user or captured by the Logic Analyzer Your PC is a Powerful Tool Take Advantage of it Using the PC Based LA 52xx and LA 55xx Logic Analyzers is an exercise in PC familiarity The PC s keyboard is used for front panel control and data input There s no need to spin dials and stumble though arcane multiple menus Typical logic analyzer offer a 9 monochrome screen The LA 52xx amp LA 55xx uses the 14 20 color monitor that came with your PC 24 channels can be displayed simultaneously in different colors while still leaving enough room for system parameters Logic Analyzer software updates are free and available via web sites With the Logic Analyzer already in the PC there s is no need to fuss with cables and communications programs in or

5. Analyzer triggers or once on the user s command Allocation of channels between the Logic Analyzer and the Pattern Generation is in groups of sixteen channels Channels can be all logic analysis all pattern generation or any multiple of sixteen for pattern generation with the remaining channels as logic analysis To select the configuration simply change the mode in the software and connect the appropriate pods the Pattern Generator Option consists of several components First is additional circuitry that is added internally to the Logic Analyzer Once added pattern generation up to the maximum number of channels of the Logic Analyzer is supported limited only by the number of pods The second are the pattern generator output pods each supporting eight outputs These are purchased in multiples of two pods 16 channels at a time Physically they are similar to the logic analyzer pods a small box with active circuitry A ribbon cable on one end connects to the analyzer box A row of standard square header pins 0 20 inch spacing at the other end provides connection points to the circuit under test The last parts are the modular clips and wires the same as those included with the logic analyzer The clips are the spring loaded double opposing hook type The 10 inch wires have female connectors at each end that fit over the pins of the pattern pod the receptacle pin of the clip or any 0 025 post For the LA 52xx amp LA 55xx series no internal ci
