They are located under the grid area, showing the parameters of the corresponding traces. Clicking the boxes creates a dialog box. See the chapter “Vertical Setup” for more details.
Page 46: Timebase And Trigger Descriptor Boxes
SDS6000L User Manual ：Ground Vertical Scale: The scale of each grid in the vertical direction. For example, when the vertical scale is 1.00 V/div, the full scale of the oscilloscope is 1.00 V/div * 8 div=8 V. Vertical Offset: The offset of the channel in the vertical direction. When the vertical offset is 0, the channel offset indicator is located in the middle of the vertical axis.
Page 47 SDS6000L User Manual Trigger delay: The time offset of trigger position. When the trigger delay is 0, the trigger delay indicator is in the center of the horizontal axis of the grid area. Horizontal scale: Timebase, the time of each grid in the horizontal direction. For example, if the scale is 500us/div, the time of each grid is 500 us, and the full-screen time range of the oscilloscope is 500 us/div * 10 div = 5 ms.

But for step signals / fast rise times, it will introduce false overshoot due to the Gibbs phenomenon.

SDS6000L User Manual 12.5M 12.5M 12.5M 125M 125M 125M 250M 250M 500M Channels 1, 2, 3, and 4 (C1~C4) are in group 1 and 5, 6, 7, and 8 (C5~C8) are in group 2  Single-channel mode: In one group, only one channel is on and in the other group, one channel or less is on.
Page 72 SDS6000L User Manual Normal mode Peak mode Average: The oscilloscope accumulates multiple waveform frames and calculates the average as the result. 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 SDS6000L, average 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 73 SDS6000L User Manual 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 74: Memory Management
SDS6000L User Manual Memory Management 11.2.3 Memory Management controls how the instrument stores the acquired samples. Auto: The default acquisition setting. After setting the maximum memory in the Auto mode, the oscilloscope automatically adjusts the sample rate and memory depth according to the time base. The adjustment principle is to follow the formula: Sample rate = number of samples/time of acquisition Where the time of acquisition is the time corresponding to the full display (i.e.
Page 75: Roll Mode
SDS6000L User Manual Roll Mode 11.2.4 Click Acquire > Roll to enter roll mode. In this mode, the waveform moves across the screen from right to left, similar to a strip chart recorder. The horizontal delay control of the waveform will be disabled when roll mode is active.
Page 76 SDS6000L User Manual In addition to minimizing the dead time, another advantage of Sequence mode is that it can capture and record rare events over long periods. The oscilloscope can capture multiple events that satisfy the trigger conditions, ignoring the periods of no interest between adjacent events, thus maximizing the use of waveform memory.
Page 77 SDS6000L User Manual 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. Set the trigger mode to "Single" and the timebase to 50 ns/div. Turn on the Sequence mode, and set the segments to maximum (46,378 in this example, up to 80,000 depending on the number of samples at the current time base).
Page 78: Esr
11.2.6 Each channel of the SIGLENT SDS6000L Oscilloscope employs a 5 GSa/s analog-to-digital-converter (ADC). After each ADC, a 2x interpolation process is applied that provides a 10 GSa/s ESR option for the users. The data flow and corresponding spectrum are shown in the figure below:...
Page 79 SDS6000L User Manual The 2x interpolation implemented is a classic sinx/x up-sampling processed by a high-speed Field Programmable Gate Array (FPGA) in real-time. The following figure shows the frequency response of the Finite Impulse Response (FIR) digital filter used in the interpolation. From the frequency response, we can see it has no attenuation at fmax = 2 GHz, and ~70 dB attenuation at 5 GHz –...
Page 80 SDS6000L User Manual Interpolation can significantly reduce this kind of error. Below is the same signal with an identical sample rate but followed by the 2x interpolation technique. From this figure, we can see points inserted between the raw data in the top/base area are closer to the real top/base of the analog input, which reduces the error.
Page 81 SDS6000L User Manual With the ESR enabled, in ERES acquisition mode, the bandwidth will be twice as scenarios without ESR: Table: ERES Bandwidth comparison between ESR disabled and enabled Enhanced Bandwidth with ESR = OFF Bandwidth with ESR = ON Resolution (5 GSa/s) (10 GSa/s)

Page 87: Trigger
SDS6000L User Manual 13 Trigger 13.1 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 an oscilloscope since we can only analyze a signal that we can trigger reliably and stably.
