8990B 峰值功率分析仪是专门用于测量和分析射频脉冲的高性能射频峰值功率计。8990B 可实现 5 ns 的上升时间/下降时间(与 N1923A/N1924A 宽带功率传感器配合使用),创造了峰值功率测量市场中的新记录,使研发工程师和技术人员可以在模块设计、验证和故障诊断过程中以高精度捕获更短的脉冲测量结果。 


8990B 拥有两个射频通道和两个视频通道,可测量射频和微波功率的动态或时间相关特性。8990B 的采样率高达 100 MSa/s,研发工程师由此可以获得需要的高分辨率来探测信号迹线中的异常情况,从而对设计进行改进。


8990B 峰值功率分析仪配有 15 英寸 XGA 彩色触摸屏,能够同时显示四个通道的结果,获得更详细的图像。8990B 提供内部和外部触发功能,以及 15 种脉冲参数测量和游标测量, 包括上升时间、下降时间、脉冲倾斜、脉冲宽度和时延等。 


8990B 与 N1923A(50 MHz 至 18 GHz)N1924A(50 MHz 至 40 GHz)宽带功率传感器结合使用,可进行性能最高的峰值功率测量。  


多脉冲测量
查看、测量和分析来自功率放大器模块或发射机的连续脉冲序列。多脉冲测量功能支持连续触发,可捕获多达 512 个脉冲。该功能还给 8990B 增添了脉冲至脉冲测量和直方分布图功能,这对于测试射频、功率放大器和发射机的脉冲至脉冲稳定度至关重要。此外,用户可以使用多脉冲测量功能来分析短脉冲(在整个脉冲序列上静寂时间较长或幅度逐渐下降),或监测脉冲形状的稳定度(通过直方图功能)。


附加功率效率运算功能
使用 8990B 可以计算功率放大器的附加功率效率(PAE),并在屏幕上即时显示 PAE 迹线。附加功率效率是一种典型的功率分析仪测量,主要衡量功率转换效率,即功率放大器将直流功率转换为射频功率的百分比。使用 8990B 还可以降低测试成本和需要使用的测试设备数量; 这款峰值功率分析仪可独立测量射频功率、电压和电流,无需再使用其他仪器。8990B 的两个射频输入通道允许用户测量功率放大器的射频功率增益;通过使用直流电流探头、示波器探头或差分探头,用户还可以测量功率放大器在模拟视频输入通道上的电压和电流。8890B 的 PAE 运算功能根据射频和模拟视频输入通道得到的这些测量结果,便能轻松计算出功率放大器的 PAE。


可调 ETS 阈值适用于更宽的带宽测量
8990B 的 160 MHz 视频带宽功能使您可以精确测量 802.11ac 宽带宽信号的峰值功率和峰均功率比。此峰值功率分析仪可以按照猝发长度调整 ETS 阈值,对 80 MHz 或 160 MHz 802.11ac 信号执行功率与时间(PvT)测量。用户还可以使用缩放功能分析和测量 802.11ac 猝发信号的前导码功率。

Calibration

  • Internal Zeroing and Calibration

The 8990B peak power analyzer is a high performance RF peak power meter specializing in the measurement and analysis of RF pulses. The 8990B achieves 5 ns rise/fall time (with the N1923A/N1924A wideband power sensor), the fastest overall rise/fall time in the peak power measurement market, allowing R&D engineers and technicians to capture shorter pulse measurements with high accuracy during the module design, verification and troubleshooting process.


The 8990B comes with two RF channels and two video channels and measures the dynamic or time-dependent aspects of RF and microwave power. With the 8990B’s sampling rate of 100 MSa/s, R&D engineers get the high resolution they need to detect abnormalities in a signal trace for design improvement.


The 8990B peak power analyzer is equipped with a 15 inch XGA color touchscreen display that is capable of simultaneously displaying four channel results for more image detail. The 8990B provides internal and external trigger functions, and comes with 15 pulse parameter measurements and markers measurements including rise time, fall time, pulse droop, pulse width and time delay.


The 8990B achieves the best performance for peak power measurement when used with the N1923A (50 MHz to 18 GHz) and N1924A (50 MHz to 40 GHz) wideband power sensors.


Multi-pulse measurement
View, measure and analyze continuous pulse trains from power amplifier modules or transmitters. The multi-pulse measurement feature allows continuously trigger and capture up to 512 pulses. This feature also adds pulse-to-pulse measurement and histogram distribution graph capabilities to the 8990B, which are crucial for testing RF and the pulse-to-pulse stability of power amplifiers and transmitters. Additionally, users can use the multi-pulse measurement feature to analyze short pulse with long off time or amplitude droop across the pulse train, or monitor the stability of the pulse shape (via the histogram graph functionality).


Power-Added Efficiency math function
Calculate the Power-Added Efficiency (PAE) of power amplifiers and display instant PAE traces onscreen with the 8990B. Power-Added Efficiency, a typical power analyzer measurement, is a measure of the power conversion efficiency – the percentage of DC power converted to RF power in the power amplifier of power amplifiers. Reduce test costs and the number of test equipment needed with the 8990B; the peak power analyzer measures RF power, voltage and current in a single solution box. The 8990B’s two RF input channels allow users to measure the RF power gain from the power amplifier; using a DC current probe, scope probe or differential probe, they can also measure the power amplifier’s voltage and current through the analog video input channels. The 8890B’s PAE math function then uses the measurements from the RF and analog video input channels to easily determine the PAE of the power amplifier.


Adjustable ETS threshold for wider bandwidth measurement
Measure peak and peak-to-average of 802.11ac wide bandwidth signal accurately with the 8990B’s 160 MHz video bandwidth capability. The peak power analyzer can execute power vs. time (PvT) measurements on an 80 MHz or 160 MHz 802.11ac signal by adjusting the ETS threshold according to the burst length. Users can also use the zoom function to analyze and measure the preamble power of the 802.11ac burst signal.
