Peak power analyser
04 July 2011
Skip the set-up and go straight to making measurements with Agilent's new 8990B peak power analyser. It offers faster measurement speed and greater measurement accuracy in peak power pulse analysis for the aerospace, defence and wireless markets. Achieve five nanosecond rise/fall time with wideband power sensors, and gain an additional channel with a U2000 series USB sensor.
The 8990B is a peak power analyser 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. It is backwards compatible with the N1921A and N1922A P-series wideband power sensors. This will enable users to leverage previous investment and lower overall cost of ownership.
Complementing the 8990B peak power analyser are the new N1923A and N1924A wideband power sensors. When combined with either sensor (N1923A or N1924A), the 8990B offers five nanosecond rise time/fall time, the fastest overall rise time/fall time in the peak power measurement market.
Built for ease of use and high performance, the 8990B peak power analyser enables users to:
• View trace displays in high resolution with a sampling rate of 100 MSa/s
• Analyse a full range of parameters with 15 predefined pulse parameter measurements, such as rise time, pulse width and duty cycle
• Verify design problems quickly with a 15 inch XGA colour and touch-screen display that can simultaneously display four channel results
• Eliminate inaccurate readings and save time on initial set-up with the internal zero and calibration function
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. It also provides internal and external trigger functions.
