Agilent Agilent E4443A是PSA系列的成员，可提供高达50 GHz的高性能频谱分析，强大的一键式测量，通用的功能集以及灵活性，速度，准确性和动态范围的领先组合。
PSA系列现代仪器架构具有全数字IF部分，高精度内部参考信号和自动内部对准过程，可实现无与伦比的精度，这是安捷伦为满足我们已发布的规格而制定的高标准所保证的。
PSA系列频谱分析仪旨在优化速度和动态范围的测量。使用2 dB步进衰减器和160分辨率带宽设置（以10％步进），您可以自定义每个测量，以实现速度和动态范围的最佳组合。
利用全数字IF，PSA可以执行扫频或FFT测量。
FFT功能可以显着减少窄范围测量和低电平杂散搜索中的扫描时间。
利用PSA系列的相位噪声优化功能，可以增加接近载波测量的动态范围。根据要测量的载波的接近或远离，PSA具有不同的LO锁相环配置，以减少相位噪声并因此增加测量的动态范围。
分析仪的时变信号，例如脉冲RF，时分多址（TDMA），交织和突发调制以及门控扫描功能。这种类型的时间选通可以对突发信号进行快速频谱测量，而不会因打开和关闭载波而产生干扰。
PSA系列提供了一套标准的，灵活的一键式RF和微波功率测量以及基于格式的设置。使用Power Suite，现在只需按一下按钮即可执行曾经难以完成的繁琐测量，并提供易于读取的结果。
一键式测量包括：信道功率占用带宽，相邻信道功率（ACP），多载波ACP功率，统计量（CCDF），谐波失真，突发功率，三阶拦截（TOI），杂散发射，频谱发射掩模。
基于格式的设置用于：
IS-95A J-STD-008。
IS-95C GSM / EDGE 3GPP W-CDMA cdma2000。
NADC PDC。
蓝牙TETRA。
W-LAN（802.11a / b / g）W-LAN HiperLAN / 2。
DVB-T。
PSA系列提供了多种可选的测量特性，以扩展测量能力。测量个性是一种软件程序，可以将频谱分析仪转换为另一种类型的测试仪器，从本质上赋予它另一个个性。
您可以使用用于频谱分析的同一台仪器轻松地进行最具挑战性的测量。
执行振荡器测试的相位噪声测量，测量放大器的噪声系数，甚至对2G或3G信号执行调制分析。如果您要测试的是专有调制信号，则可以将PSA链接到89601A矢量信号分析软件，以进行灵活的解调和分析。
PSA系列具有与PC，打印机，软件程序和测试系统联网的内置功能。功能包括IVI-COM驱动程序，用于开发测量程序并收集结果。
IntuiLink连接软件可将测量结果和屏幕截图直接传输到Microsoft Excel和Word中，后者是用于存储结果和显示数据的软盘驱动器，以及用于SCPI编程的GPIB和10 baseT LAN。您也可以使用BenchLink Web远程控制软件（选件230）在世界任何地方远程操作分析仪。
The Agilent Agilent E4443A is a member of the PSA series, offering high-performance spectrum analysis up to 50 GHz with powerful one-button measurements, a versatile feature set, and a leading-edge combination of flexibility, speed, accuracy, and dynamic range.
The PSA Series modern instrument architecture features an all digital IF section, a highly accurate internal reference signal, and automatic internal alignment processes to achieve unsurpassed accuracy, guaranteed by Agilents high standards for meeting our published specifications.
The PSA Series spectrum analyzer is designed to optimize measurements for speed and dynamic range. With a 2-dB step attenuator and 160 resolution bandwidth settings (in 10% steps), you can customize each of your measurements to achieve the best combination of speed and dynamic range.
With the all-digital IF, the PSA can perform both swept or FFT measurements.
FFT capability can significantly reduce the sweep time in narrow span measurements and low-level spur searches.
Increase the dynamic range of your close-to-carrier measurements with the phase noise optimization feature of the PSA Series. Depending on how close to or far from the carrier you are measuring, the PSA has different LO phase lock loop configurations to reduce phase noise and therefore increase the dynamic range of your measurement.
Analyzer time varying signals such as pulsed RF, time division multiple access (TDMA), interleaved and burst-modulated with gated sweep capability. This type of time gating makes fast spectrum measurements on burst signals without interference from switching the carrier on and off.
The PSA Series offers a standard suite of flexible, one-button RF and microwave power measurements with format based setups. With Power Suite, measurements that were once difficult and tedious to make are now executed with a single button press and provide easyto- read results.
One-button measurements include: channel power occupied bandwidth, adjacent channel power (ACP), multi-carrier ACP power, statistics (CCDF), harmonic distortion, burst power, third order intercept (TOI), spurious emissions, spectrum emission mask.
Format-based setups for:
IS-95A J-STD-008.
IS-95C GSM/EDGE 3GPP W-CDMA cdma2000.
NADC PDC.
Bluetooth TETRA.
W-LAN (802.11a/b/g) W-LAN HiperLAN/2.
DVB-T.
The PSA Series offers a variety of optional measurement personalities to expand measurement capability. A measurement personality is a software program that can transform the spectrum analyzer into another type of test instrument, essentially giving it another personality.
You can make the most challenging measurements very easily and with the same instrument you use for spectrum analysis.
Perform phase noise measurements for oscillator tests, measure the noise figure of your amplifier, or even perform modulation analysis on your 2G or 3G signal. If you have a proprietary modulated signal that you want to test, you can link the PSA to the 89601A vector signal analysis software for flexible demodulation and analysis.
The PSA Series has built-in capability to network with PCs, printers, software programs, and test systems. Features include IVI-COM drivers for developing measurement routines and collecting results,.
IntuiLink connectivity software to transfer measurement results and screen captures directly into Microsoft Excel and Word, a floppy disk drive to store results and display data, and GPIB and 10 baseT LAN for SCPI programming. You can also operate the analyzer remotely, anywhere in the world, using our BenchLink Web Remote control software (Option 230).
