Agilent 8990B 峰值功率分析儀采用簡單易用和高性能的設計，并配備了15英寸 XGA 彩色觸摸屏，Agilent 8990B 峰值功率分析儀可同時顯示四個通道結果，提供更多的圖像細節。Agilent 8990B 峰值功率分析儀提供高達 100 MSa/s 的采樣率，研發工程師由此可以獲得所需的高分辨率來探測信號跡線中的異常情況，從而對設計進行改進。
Agilent 8990B 峰值功率分析儀提供了15種預定義的脈沖參數測量，包括上升時間、脈沖傾斜、脈寬和時延等。用戶只需在觸摸屏上進行兩步簡單操作，便可讓測量自動完成。這些參數可用于功率放大器、TR 模塊、應答機、雷達測試儀和衛星凈荷以及其他測試設備的設計、測試和驗證，使工程師不必再進行復雜的脈沖測量。

Agilent 8990B 峰值功率分析儀描述
The 8990B is a peak power analyzer that consists of two RF channels (1 and 4) and two video channels (2 and 3). When used with a compatible peak power sensor, the 8990B is able to measure the dynamic or time- dependent aspects of RF and microwave power. A combination of the 8990B and the N1923/4A peak power sensor enables the RF pulse rise/fall time measurement of up to 5 nsecs. The video inputs of the 8990B allow the simultaneous analysis of time- domain control signals.
The 8990B has a frequency range of 50 MHz to 40 GHz and a dynamic power range of –35 dBm to 20 dBm, depending on the peak power sensor used. The 8990B is capable of measuring peak power, minimum power, average power, peak- to- average power, pulse repetition interval, pulse repetition rate, rise time, fall time, pulse off time, pulse top, pulse base, pulse width, duty cycle, and overshoot. The 8990B also provides internal and external trigger functions.
Below are the wideband power sensors design specifically for 8990B to achieve the best performance for peak power measurement.
N1923A (50 MHz to 18 GHz)
N1924A (50 MHz to 40 GHz)
