Page 38 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. Rear Panel Four rear panel connectors (see Figure 2- -1 on page 2- -2) connect the logic analyzer module to the backplane of the mainframe.
Page 39 You must jumper the pins when updating the flash image. The logic analyzer module is shipped without a jumper installed on these pins. Refer to the Tektronix Logic Analyzer Family User Manual for instructions on upgrading the firmware. Online Help Most user information for operating the logic analyzer module is available through the online help within the Tektronix Logic Analyzer Series application.
Page 40 Operating Information NOTE. Performing the self calibration does not guarantee that all logic analyzer module parameters operate within limits. Operation within limits is achieved by performing the Adjustment Procedures. Proper operation may be confirmed by performing the performance verification procedures in this same manual. When to Perform the Self Calibration.

Page 45 Theory of Operation The basic logic analyzer module consists of two main circuit boards: the LPU (local processor unit) board and the acquisition board. The logic analyzer modules with 102 or 136 channels also have one and two (respectively) comparator daughter boards present. Up to eight probes acquire data from a system under test and send it to the logic analyzer module for processing.
Page 46: Table 3- 1: Local Processor Unit Board Fuses
Theory of Operation Power Supplies.The Power Supplies receive +5 V, - -5.2 V, +12 V, and +24 V from the mainframe through the rear connectors to power the logic analyzer module. Fuses protect the mainframe from over-current conditions. Voltage converters produce additional +5 V and +3.5 V supplies for use on the Acquisi- tion board.
Page 47 Theory of Operation Acquisition System. Acquired data from the probe interface is sent to the data recognition circuitry. The data recognition circuitry analyzes the acquired data and determines which data to qualify and send to the acquisition memory. It also sends trigger event signals to the trigger and storage circuitry.
Page 48 Theory of Operation Merged Modules A merged module consists of a Master module and a Slave module 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 module.
