Every grid is 8 Vertical divisions representing the full number of 256 Vertical levels and 10 Horizontal divisions representing the total acquisition time. The value of each division depends on the Vertical and Horizontal scale of the traces that appear on that grid.

  • Page 49: Waveform Acquisition

    Waveform Acquisition Waveform Acquisition Topics in this section explain how to configure the instrument to acquire new waveforms. Auto Setup Auto Setup configures the essential acquisition settings based on the first input signal it finds, starting with C1. If nothing is connected to C1, it searches C2 and so forth until it finds a signal. Vertical Scale (Volts/div), Offset, Timebase (Time/div), and Trigger are set to a 50% Edge trigger on the first, non-zero-level amplitude, with the entire waveform visible for at least 10 cycles over 10 horizontal divisions.

When a Teledyne LeCroy probe is connected to a channel input, the Attenuation field becomes a button to access Probe dialog, a tab added to the right of the Cn tab.
  • Page 52 LabMaster Oscilloscope Systems Operator's Manual Invert changes the apparent polarity of the signal, substituting an equivalent negative value for a positive one, and vice versa, so that the waveform appears to be "flipped" on screen. De-Embedding allows you to remove the effects of cables used to input signals. On oscilloscopes with the Cable De- embedding option installed, select the checkbox, then enter the attenuation constants or cable characteristics (provided by the cable manufacturer) on the Cable De-Embedding dialog that appears.

  • Page 53: Cable De-Embedding Option

    Waveform Acquisition Cable De-Embedding Option Losses in the cables used in the test setup can reduce the accuracy of your signal (e.g., signal amplitude and rise time), as well as introduce Inter-Symbol Interference. These cable effects can dramatically alter measurements and potentially create mask test violations.

    Auto Zero corrects for DC offset drifts that naturally occur from thermal effects in the amplifier of active probes. Teledyne LeCroy probes incorporate Auto Zero capability to remove the DC offset from the probe's amplifier output to improve the measurement accuracy.

    Waveform Acquisition LabMaster Deskew Calibration The ChannelSync™ architecture in LabMaster modular oscilloscope systems utilizes a single 10 GHz distributed clock for all acquisition modules. This provides precise timing alignment and timing accuracy between all channels in all acquisition modules as found in a single, conventional oscilloscope package. However, to ensure that the static skew of all connecting cables is accounted for, a calibration at the time of system set up, and periodically thereafter, is required for the most accurate results.

  • Page 69: Trigger

    Waveform Acquisition Trigger Triggers define the event around which digitized information is displayed on the grid. Different Trigger Types are used to select different events in the trigger source waveforms: edge voltages, pulse widths, high/low states, etc. These may be a single-channel event or a complex pattern of events across several channels.

  • Page 70: Trigger Types

    LabMaster Oscilloscope Systems Operator's Manual Trigger Types The Trigger Type sets the triggering conditions. Edge triggers upon a achieving a certain voltage level in the positive or negative slope of the waveform. Width triggers upon finding a positive- or negative-going pulse width when measured at the specified voltage level. Pattern triggers upon a user-defined pattern of high and low voltage levels on selected inputs.

  • Page 71: Trigger Setup

    Waveform Acquisition sources that may be used with several types of triggers, most usually Edge triggers that fire upon the occurrence of a particular edge and level of the trigger input. External triggers (Ext source) look for the selected slope and level in an externally generated pulse that is input to the oscilloscope's Ext.
  • Page 72 LabMaster Oscilloscope Systems Operator's Manual Coupling For analog triggers, specify the type of signal Coupling at the input: DC - Frequency components are coupled to the trigger circuit for high frequency bursts, or where the use of AC coupling would shift the effective trigger level. AC - Capacitively coupled.
  • Page 73 Waveform Acquisition The extent of the range can often also be specified by using a Nominal and Delta value, rather than an absolute upper and lower value. In this case, the Nominal value sets the center of the range, and the Delta determines how many units plus/minus the Nominal value are included in the range.

  • Page 79: Trigger Holdoff

    Waveform Acquisition Trigger Holdoff Holdoff is either a period of time or an event count that may be set as an additional condition for Edge and Pattern triggers. Holdoff disables the trigger temporarily, even if the other conditions are met. Use Holdoff to obtain a stable trigger for repetitive, composite waveforms.
  • Page 80 LabMaster Oscilloscope Systems Operator's Manual Hold Off by Events Events refers to the number of times the trigger conditions have been met following the arming event. For example, if the Holdoff is two edges counted from the start of the acquisition, the oscilloscope readies, arms on the first edge, holds off for the next two, triggers on the fourth edge, then completes the acquisition.

  • Page 81: Software Assisted Trigger

    Waveform Acquisition Software Assisted Trigger Software Assisted Trigger is used to find the trigger-level crossing point closest to the hardware trigger point. It then adjusts the time offset of the waveform so that it is aligned with the specified trigger level and slope. In the following figure, the white trace is the waveform at the input to software-assisted trigger processing.
  • Page 82 LabMaster Oscilloscope Systems Operator's Manual TriggerScan TriggerScan is a debugging tool that helps you quickly discover waveform anomalies by automating the process of building triggers designed to find rare events in an acquisition. Triggerscan trains the system by looking at acquired waveforms. During the training, TriggerScan analyzes the waveforms to determine what waveforms normally look like.
