波形細節清晰可見
12-bit ADC：waveform details are clearly visible

SDS3000X HD 系列示波器配備 12-bit 高解析度 ADC，量化階層高達 4096 級；在增強解析度模式 (ERES) 下，解析度更可提升至 16-bit。結合垂直與水平縮放功能，能協助使用者以更完整、清晰的方式觀察波形細節。

SDS3000X HD series oscilloscopes are equipped with 12-bit high-resolution ADC, with quantization level up to 4096, and the resolution can be increased to 16-bit in high-resolution mode (ERES), which together with the vertical and horizontal zoom functions, helps users observe the details of waveforms in a more complete and clearer way. 

ENOB - 有效位元數
ENOB - Effective Number of ADC Bits

當高速 ADC 進行數據擷取時，受限於雜訊與失真，實際 ADC 的訊號雜訊失真比 (SINAD) 通常無法達到其標稱位元數所應有的理想性能。由於 ADC 僅是示波器系統的一部分且無法獨立運作，因此「整個示波器系統」的 ENOB 指標更具實際意義。
SDS3000X HD 系列的有效位元數高達 8.2 至 8.5 位元，具備更低的時間誤差與頻率雜散，能有效確保量測的精準度。

When a high-speed ADC performs data acquisition, the signal-to-noise-to-distortion ratio of the actual ADC falls short of the desired performance that its nominal number of bits should achieve due to noise and distortion.  Since the ADC is only a part of the oscilloscope system and cannot be used independently, the ENOB indicator of the whole oscilloscope system will be more meaningful.
SDS3000X HD is up to 8.2 to 8.5-bit, with less time error and frequency spuriousness, which can effectively ensure the accuracy of measurement.

多樣化觸發類型
Multiple trigger types

SDS3000X HD 系列示波器提供多種觸發類型，包括邊緣觸發 (Edge)、間隔觸發 (Interval)、視訊觸發 (Video)、串列匯流排觸發 (Serial Bus) 及區域觸發 (Area Triggering) 等。其中，「區域觸發」有別於傳統觸發方式，適用於參數特性尚不明確的偶發訊號；使用者僅需透過滑鼠或觸控螢幕，即可建立並定義一個區域來完成訊號擷取。

匯流排觸發支援 I2C、SPI、CAN、CAN FD、FlexRay、I2S、MIL-STD-1553B、SENT 等多種協定，為嵌入式系統、車用電子、電腦及其他串列匯流排提供完整的測試解決方案。

SDS3000X HD series oscilloscopes provide a variety of trigger types, including edge, interval, video, serial bus, area triggering, etc. Among them, area triggering is different from traditional triggering, which can be applied to episodic signals whose parameter characteristics are not yet clear, and the signal capture can be completed by creating and defining an area using only the mouse or touch.
Bus trigger supports I2C, SPI, CAN, CAN FD, FlexRay, I2S, MIL-STD-1553B, SENT and other buses, providing test solutions for embedded, automotive, computer and other serial buses.

電源分析：快速取得電源參數 (Power Analysis)
Power analysis：quickly get power parameters

SDS3000X HD 可選配電源分析功能，搭配鼎陽科技（Siglent）的電壓探棒（如 DPB5000 系列）與電流探棒（如 CP6000 系列），能快速且精確地分析電源品質、電流諧波、湧浪電流 (Inrush current)、暫態響應等 12 項電源供應器關鍵參數。
例如，透過將切換損耗 (Switching loss) 降至最低，能有效提升電源效率；此外，藉由計算電源元件暫態數值在各種工作條件下超出安全工作區 (SOA) 的機率，能精確評估設備的運作穩定性。

SDS3000X HD can be equipped with optional power supply analysis function, together with Siglent's voltage probes (e.g., DPB5000 series) and current probes (e.g., CP6000 series), it can quickly and accurately analyze 12 parameters of power supply such as power quality, current harmonics, inrush current, transient response, etc.
For example, to improve the efficiency of the power supply by minimizing switching loss, to evaluate the working stability of the device by counting the probability that the power device transients exceed the safe working zone under all working conditions. 

50 MHz 波形產生器 (Waveform Generator)
50MHz waveform generator

SDS3000X HD 可透過 USB 介面直接連接 SAG1021I 波形產生器。SAG1021I 具備 125 MSa/s 取樣率與 14-bit 解析度，可輸出最高達 50 MHz 的預定義波形，包含正弦波、方波、三角波、脈衝波、雜訊、直流訊號，以及 45 種內建的任意波形。
