詳細介紹
GDS-3000A系列示波器提供每個通道高達200Mpts的記錄長度,超長記錄長度的優點允許用戶即使在低速時間設置下也能保持較高的采樣率。當采樣率比測試頻率高兩倍時,它可以確保捕獲的信號沒有失真,這有利于在低速下長時間觀察信號的變化,這對信號的深入分析非常有幫助。
關于波形更新率,GDS-3000A高達200,000 wfm/s,用戶可以輕松觀察到零星的異常信號。分段存儲器可連續捕獲多達490,000個分段,可與觸發條件設置配合使用,跳過長時間未改變的波形,只記錄有意義的波形,從而提供有效的內存使用方法。分段內存下還提供掩碼功能,允許用戶快速確定大量信號是否超出目標范圍,并可以快速搜索錯誤波形的時間和實際信號。
在測量功能方面,提供了38種測量項目。精細刻度功能可使用戶根據需要微調垂直刻度,以實現全尺寸測量并提高電壓或電流測量的精度。提供了高分辨率模式的采集方法,有效地消除了噪聲,提高了自動測量的精度。屏幕顯示器右側提供了動態垂直刻度顯示器,使用戶更容易解釋與測量信號相對應的垂直振幅。標準的1 MΩ和50Ω輸入阻抗的選擇允許用戶根據不同的測量要求選擇輸入阻抗,以實現阻抗匹配。搜索功能可以根據用戶設置快速查找合格信號,這對于查找和比較零星波形非常有幫助。
光標標記功能允許用戶清楚地觀察光標測量的點之間的電壓(或電流)、時間和增量數據。使用指示器功能,可以通過顯示波形的部分來顯示測量范圍。
在頻域測量方面,GDS-3000A提供了FFT測量功能和雙通道頻譜分析儀。用戶可以同時測量和分析雙通道頻域信號。光譜圖功能允許用戶輕松觀察頻譜分布隨時間的關系,以便觀察信號的頻譜特性。
GDS-3000A為開關電源測試提供了豐富的測試項目。提供的電源測試項目包括交流輸入分析項目:電源品質、諾波、浪涌電流;直流輸出分析所需測試項目:紋波/噪聲、瞬態響應分析、開/關分析、效率;控制回路響應(Bode)和電源抑制比(PSRR);完整的開關元件分析項目:調制、開關損耗、SOA( 安全工作區)和磁性分析: B-H 曲線。GDS- 3000A內建50MHz(GCP-530)和100MHz(GCP-1030)電流探棒的電源。此功能可以節省用戶購買電流探頭電源的成本,減輕外出攜帶電流探頭電源的負擔。
GDS-3000A標配雙通道25MHz任意波發生器。用戶可以選擇任意波功能來存儲模擬通道測量的信號或直接從信號發生器輸出。此功能允許用戶方便地生成各種類型的測量信號,以模擬各種信號輸出。還配備了頻率響應分析功能(Bode Plot),可應用于產品電路和元件特性驗證與分析,包括RLC電路設計、濾波器設計和放大器設計驗證與分析。
GDS-3000A提供豐富的通信接口。除了常用的USB Host、USB設備端口和LAN端口外,它還包括一個高度穩定的RS232接口和一個選配的GPIB接口。
