Highlights
- 以高達 1 MSa/s 的高速運作
- 具備 1,240 nm 至 1,650 nm 的波長運作範圍
- 以典型的 1.5° 偏振狀態（SOP）量測不確定性
- 堅固耐用，沒有移動的光學零件
Keysight N7781C 是一款外形小巧的高速偏振分析儀，提供分析光信號偏振特性的完整功能。 包括龐加萊球（Stokes 參數）的偏振狀態（SOP）呈現。 內建的演算法以及內建的校驗資料，確保可在寬廣的波長範圍內，維持高度準確的操作。
該儀器具有每秒 1 M 取樣的即時量測能力，非常適合用於分析干擾和波動信號，以及需要即時回授極化資訊的控制應用，例如自動化製造測試系統中的數位控制迴路.
內建的操作介面可全面分析所獲得的量測資料，可取代 N7781B（N7781C 的前身）所需的偏振導航軟體。 它使用新的可編程儀器（SCPI）指令集來編寫程式，並可充當 VISA 資源來使用。 此輕巧型儀器僅 1 U 高，配備 LAN 和 USB 介面。
