  • Page 6 The HDA125 is a powerful solution for the challenge of measuring multiple, mixed signals in a single oscilloscope. An accessory for the Teledyne LeCroy Zi series oscilloscopes, the HDA125 extends their testing range by adding 9 or 18 digital channels for waveform display or triggering.

    QuickLink probing system. The HDA125 is ideally suited for embedded system testing where there is a proliferation of analog signals coincident with digital signals. You can easily debug signals using standard oscilloscope tools such as cursors, measurement parameters, and zooming.

    HDA125 High-speed Digital Analyzer Safety Observe these instructions to keep the product operating in a correct and safe condition. Follow generally accepted safety procedures in addition to the precautions specified here. The overall safety of any system incorporating this product is the responsibility of the assembler of the system.
  • Page 9 Operator’s Manual grounded mating outlet. Connect and disconnect properly. Do not connect/disconnect probes or test leads while they are connected to a live voltage source. Exercise electrostatic discharge (ESD) precautions. The digital leadsets and probe tips are sensitive to ESD. When making connections to the device under test, always wear a grounding wrist strap.

  • Page 10: Technical Overview

    HDA125 High-speed Digital Analyzer Technical Overview The HDA125 is an external device that digitally samples waveform data at up to 12.5 GS/s (enabling acquisition of digital signals up to 6 Gb/s). Unlike a logic analyzer, it operates only in a Timing Analysis mode, so it requires oversampling to determine the correct digital edge position, and does not require the user to input a clock.

    (wear wrist strap, etc.) when using or handling the equipment. Order of Operations To ensure that all components (HDA125 and leadset) are correctly identified by the system software, the following order of operations is recommended: 1. Close the oscilloscope application, or shut down the oscilloscope.

  • Page 13: Connecting The Digital Leadset

    Operator’s Manual Connecting the Digital Leadset Connect the digital leadset to the digital input on the front of the HDA125. Push the connector until it “snaps” into place. When removing the leadset, press the tabs on both sides of the connector head, then pull out.

  • Page 14: Connecting Hda125 To The Oscilloscope

    Connecting HDA125 to the Oscilloscope Oscilloscopes with an LBUS Interface Connect the LBUS cable from the LBUS connector on the back of the HDA125 to the LBUS connector on the back of the oscilloscope. Be sure the head is turned so that the wedge fits into the groove at the top of the connector.
  • Page 15 Operator’s Manual Oscilloscopes with a ChannelSync Interface The ChannelSync interface is used to connect the HDA125 to LabMaster systems. NOTE: In systems based on the LabMaster Master Control Module, be sure to connect at least one Acquisition Module to the MCM Zi (as described in the LabMaster Operator’s Manual) before connecting the HDA125.

  • Page 16: Connecting Ql-Si Tips To The Digital Leadset

    HDA125 High-speed Digital Analyzer Connecting QL-SI Tips to the Digital Leadset Solder the QL-SI tips to the device under test, then insert the connector head of the tip into the leadset pod, matching the tip color to the port color.

  • Page 17: Connecting Ql-Si Tips To The Quicklink Adapter

    Any QL-SI tip can be connected to a WaveLink™ Low-bandwidth or Medium- bandwidth Modular Differential Probe using the QuickLink™ Adapter (sold separately from the HDA125) in order to view the signal as an analog waveform. There is no need to remove the tip from the device under test; just remove the QL-SI connector head from the digital leadset pod and insert it into the QuickLink Adapter.

  • Page 18: Deskewing

    HDA125 High-speed Digital Analyzer Deskewing Before using the HDA125, it is crucial to deskew the signal path to ensure proper signal timing. Since the HDA125 is typically used in embedded applications, it is assumed that it will be used in conjunction with differential analog probes capturing signals on the oscilloscope’s analog channels.
  • Page 19 SMA cable can be used to terminate the PCF200 to one of the oscilloscope’s outputs. 5. Connect the QL-SI tip to one of the empty slots in the HDA125 connector pods. 6. Go to Vertical > Digital1 Setup and create the Digital1 group with only the line that you connected to the PCF200.
  • Page 20 10. Touch the Digital1 descriptor box to open the Digital1 dialog, then touch Store to save the FastEdge trace to memory. 11. Disconnect the HDA125 connector pod from the PCF200 adapter, and connect the first probe to be deskewed.
  • Page 21 Operator’s Manual 12. Touch the Cx descriptor box to open the channel dialog and adjust the channel’s Deskew value so that the 50% rising edge point matches the rising edge stored in memory, as shown below: 13. Now, decrease the timebase to around 20 ps/div and adjust the Deskew value so that the 50% rising edge point is centered in time.

  • Page 22: Digital Setup

    Skew The Skew setting is useful in cases where the HDA125 is being used to acquire several signals that are time-aligned, but the QL-SI tips have been soldered to the bus in a “staggered” fashion, thus introducing skew between the signals.

  • Page 23: Digital Group Setup

    Operator’s Manual Digital Group Setup This procedure organizes the digital lines into groups, which correspond to buses. Lines generally correspond to the physical QL-SI tips, although any tip can be assigned to any line number (and color) to make it easier to assemble groups without having to disconnect tips from the test device.

  • Page 24: Renaming Digital Lines

    HDA125 High-speed Digital Analyzer Renaming Digital Lines You can give each line a user-defined name to make the interface more intuitive. Touch the Dx button immediately below the Dx selection checkbox (the words "Change Line Name" appear at the far left of the row). Use the virtual keyboard that appears on the touch screen to enter a new name.
  • Page 25 Operator’s Manual Change Trace Style You can also change the Display Mode setting to view a digital Bus trace that collapses all the lines in a group into their Hex values, or both Lines and Bus. The size and placement of the lines depend on the number of lines, and the Vertical Position and Line Height settings.

  • Page 27: Pattern Trigger

    Operator’s Manual Pattern Trigger Digital Pattern is the default trigger when the HDA125 is connected to the oscilloscope. However, a Pattern trigger can also be set on a user-defined pattern of High or Low voltage levels on analog channels (including the External Trigger input), or a combination of digital and analog patterns.
  • Page 28 HDA125 High-speed Digital Analyzer Digital Pattern Using Logic If you have not set up digital groups, you can set a digital pattern line by line using the Logic method. All available lines remain active for selection. At the far right of the Digital Pattern dialog, choose Logic.
