Page 52 Deskew Due to the skew between channels, cables or probes, the delay of signals passing through different measurement paths may be inconsistent. For example, two coaxial cables with a 1 inch difference in length could introduce a skew of more than 100 ps.
Page 53: Digital Channels
Before invert After invert 12 Digital Channels 12.1 Overview The logic probe is designed to monitor up to 16 digital signals simultaneously. The 16 digital channels are separated into two groups and each group has its own threshold, making it possible to simultaneously view data from different logic families.
Page 54 The equipment shall be used only for the purposes specified by the manufacturer. The logic probe is used only for Teledyne LeCroy’s T3DSO series oscilloscopes. Protection mechanisms can be compromised if the way the devices connected by the logic probe are not used for their intended purpose.

Page 59: Horizontal And Acquisition Setup
13 Horizontal and Acquisition Setup 13.1 Timebase Setup The timebase setup is used to adjust the scale and offset of the X (horizontal) axis. This setting applies to all analog, digital channels and all math traces except FFT. Touch the timebase descriptor box, the quick menu of the timebase settings will pop up.
Page 60: Acquisition Setup
With 250 Mpts memory depth, T3DSO3000 can still run at full sample rate (5 GSa/s) even when set to the 5 ms/div timebase.
Page 61 Note: The memory depth here is the upper limit of the memory space allocated by the oscilloscope. The actual sample points is related to the current timebase and may be less than memory depth. The actual sample points information can be obtained in the timebase descriptor box (see the section “Timebase and Trigger”...
Page 62: Acquisition
Gibbs phenomenon. X Interpolation Sinc Interpolation Acq mode: "Fast" is the default setting. The T3DSO3000 provides a very high waveform update rate in fast mode. "Slow" mode will slow down the waveform update rate intentionally. 13.2.2 Acquisition The acquisition mode is used to determine how to acquire and process the signal.
Page 63 If a stable trigger is available, the resulting average has a random noise component lower than that of a single-shot record. The more frames that are accumulated, the lower the noise is. For the T3DSO3000, 55 User Manual...
Page 64 (SNR) is improved. As a result, the effective number of bits (ENOB) of the oscilloscope is enhanced. For the T3DSO3000, ERES processing is implemented by the hardware engine, so it can still maintain a high waveform update rate when the acquisition mode is set to average.
Page 65: Roll Mode
Normal mode ERES mode (3-bit) ERES acquisition does not require the signal to be periodic, nor does it require stable triggering, but due to the digital filtering, the system bandwidth of the oscilloscope will degrade in ERES mode. The higher the enhanced bits, the lower the bandwidth.
Page 66: Sequence
If sequence mode is enabled, the display will not update until all of the sequences have been acquired. The T3DSO3000 can achieve a minimum 2 us trigger interval in Sequence mode, corresponding to a waveform update rate of 500,000 wfm/s.
Page 67 After the acquisition is finished, the oscilloscope will map all the segments together to the screen. If you need to view and analyze each frame separately, history mode will help (see the section “History” for details). History mode provides timestamp labels for each segment. In addition to minimizing the dead time, another advantage of Sequence mode is that it can capture and record rare events over long time periods.
Page 68 Set the coupling mode of C1 to DC50Ω, and vertical scale to 500 mV/div, vertical offset to 0. Set the trigger level to 0. In normal mode, 5 pulses can be obtained on the screen with the sample rate of 1.25 GSa/s at the maximum memory depth.
Page 69 In Sequence mode, there is no waveform displayed on the screen until the acquisition is completed. During acquisition, there is a counter on the screen indicating the number of segments that have been acquired. In the example, 53969 pulses can be obtained with the sample rate of 5 GSa/s at the maximum memory depth.

Page 76: Trigger
14 Trigger 14.1 Overview The oscilloscope only acquires waveforms of interest (i.e. the ones that satisfy the trigger condition) and aligns all trigger events at the trigger position to form a stable waveform display. The trigger is one of the most important features of any oscilloscope, since we can only analyze a signal that we are able to trigger in a reliable and stable manner.
Page 77: Trigger Setup
Trigger settings should be based on the features of the input signal. For example, a sine wave with repeatable period can be triggered on the rising edge; for capturing hazards in a combinational logic circuit, the pulse trigger can be set.
Page 78 A. Select trigger type B. Select the trigger source C. Select the trigger slope (When the trigger type is “Edge”, “Slope” and other specific types) D. Set holdoff (None/Time/Events) E. Set trigger coupling mode (DC/AC/LF Reject/HF Reject) F. Enable/disable Noise Rejection. When Noise Reject is on, the trigger hysteresis is increased, so the noise immunity of the trigger circuit is better.
Page 79: Trigger Level
14.3 Trigger Level Both analog and digital triggers must have a correct trigger level value. The oscilloscope judges whether a waveform satisfies the trigger condition when it crosses the trigger level. If it does, the crossing time is the trigger position. In the following figure, the trigger condition is set as rising edge.
Page 80: Trigger Type
� Rare events 14.5 Trigger Type 14.5.1Overview The trigger modes of the T3DSO3000 are digital designs. Compared with analog trigger circuits, digital triggers can not only greatly optimize trigger precision, trigger jitter, but also support multiple trigger types and complex trigger conditions.
