    Troubleshooter to stimulate the UUT makes it an effective tool for signature-type fault isolation methods. The Asynchronous Signature Option 9000A-006 provides additional Troubleshooting capability for the 9000A series Troubleshooters by using signature-type fault-isolation, events counting, and test-node waveform capture. Control signals from the UUT establish the signature and allow asynchronous operation with respect to the microprocessor bus cycle, i.e., the Pod.

  • Page 10: Equipment Description

    9000A-006 Service EQUIPMENT DESCRIPTION 1-2. General 1-3. As shown in Figure 1-1, the Asynchronous Signature option consists of the Asynchronous Signature Module mounted within the Troubleshooter case, a separate Clock Module that connects to the Troubleshooter, and operating programs contained on a magnetic tape cassette.

  • Page 11: The Clock Module

    9000A Series Troubleshooter are documented in the appropriate manual(s). Note Information for operating and programming the Asynchronous Signature Probe is available in a separate manual. Order John Fluke Part Number 773259. SPECIFICATIONS 1-8. Table 1-1 lists the specifications for the Asynchronous Signature Probe Option.
  • Page 12 9000A-006 Service Asynchronous Signature Probe Option Specifications TABLE 1-1. SYNCHRONIZATION AND CONTROL Start Event: A selectable positive or negative edge on the Start line, or the Sync signal from the Interface Pod (when used). Stop Event: A selectable positive or negative edge on the Stop line, or the Sync signal from the Interface Pod (when used).
  • Page 13 The 32 samples terminate with the stop event. SYSTEM COMPATIBILITY Can be installed in the Fluke 9005A, 9010A, and 9020A mainframes. Cannot be used with 1802 interface pods. PROGRAM CONTROL All functions of the Asynchronous Signature Probe Option can be commanded from within a 9010A or 9005A user program.

    9000A-006 Service Section 2 Theory of Operation INTRODUCTION 2-1. This section contains two block diagram descriptions of the Asynchronous Signature Module housed within the case of the 9000A Series Troubleshooter. The first block diagram description is general; it describes the operating concept of the Signature Module and its relationship to the Troubleshooter and UUT.
  • Page 16 9000A-006 Service Figure 2-1 shows that the Signature Module is connected across the pod bus. Connection to the bus allows the transmission of op codes and data to the module. Connection to the bus also allows the transmission of signature, events count, waveform data, and module status back to the Troubleshooter.

  • Page 17: Signature Module, General Block Diagram

    9000A-006 Service FIGURE 2-1. Signature Module, General Block Diagram The START, STOP, CLOCK, and ENABLE signals from the UUT are conditioned by the Clock Module and applied to the gate section of the module. The gate section also accepts the pod SYNC signal (produced by the Interface Pod) as a control signal. The main function of the gate section is to provide gated CLOCK signals to the CRC and events registers.

    9000A-006 Service placed on the bus until commanded to do so by the Troubleshooter. Since only four bits of signature data are placed on the pod bus at a time, four read operations are required by the Troubleshooter to shift all four characters of signature data through the CRC section and onto the bus.

  • Page 20: Control Section Block Diagram

    9000A-006 Service The Interface Pod and the Signature Module are both connected to the same I/0 port of the Troubleshooter, and the Signature Module examines each op code placed on the pod bus (by the Troubleshooter) to determine if the Signature Module should turn on or if the Interface Pod should be allowed to respond.
  • Page 21 9000A-006 Service When the Troubleshooter places a command (op code) on the pod bus destined for the Interface Pod, it pulls the MAINSTAT signal low. The MAINSTAT signal is fed through delay circuit U29/U52 and gate U37 out to the interface pod as the SW-MAINSTAT signal.

  • Page 22: Gate Section

    9000A-006 Service Gate Section 2-6. The main function of the gate section is to provide gated CLOCK pulses, using the START, STOP, CLOCK, ENABLE, and pod SYNC signals, as selected by the operator of the Troubleshooter. The gated CLOCK signals are required by the CRC section to clock in the data appearing at the data probe and to calculate the signature of the data occurring during the gate time.

  • Page 23: Gate Section, Block Diagram

    9000A-006 Service Assuming no STOP edge has yet been received, and assuming the enable level is in the enabled state, the enable gate (U49) provides a GATE-ON signal to the clock gate (U24 and U23) (and to the events and waveform sections).

  • Page 24: Crc Section

    9000A-006 Service Clock counter (U20A, U8 U9, U10) creates a STOP edge after a certain number of gated CLOCK pulses. This feature allows selection of agate time that is equivalent to a specified number of gated clock pulses. The clock counter receives the gated CLOCK pulses fed to the CRC and events sections and decrements from a preset (at the time of initialization) count.

  • Page 25: Events Section

    9000A-006 Service FIGURE 2-4. CRC Section, Block Diagram Events Section 2-8. The events section contains a 24-bit binary counter that consists of six 4-bit registers, U57 through U62. Each register has four-bit parallel inputs and outputs, where the output of the first is connected to the input of the second, etc.

  • Page 26: Waveform Section

    9000A-006 Service FIGURE 2-5. Events Section, Block Diagram Waveform Section 2-9. The function of the waveform section is to read the probe data on a continuous basis so that it always contains the last 640 nanoseconds of probe data in a binary form. Figure 2-6 shows that the waveform section consists of four 16-bit shift registers, each made up of two 8-bit shift registers connected in series.

  • Page 28 9000A-006 Service At the end of a read probe operation (at the end of the gate time), the signature module transmits the waveform data to the Troubleshooter by first halting the 25 MHz shifting action of the registers. With the registers halted, the serial outputs of the four registers apply the oldest nibble of waveform data to the parallel input of the event counter.
