E8244A是安捷伦的40 GHz射频发生器。射频发生器是工程师在测试电子设备时用来产生正弦输出的工具。输出将自动改变其频率或在频率之间扫描。“扫描”是频率变化的一个完整周期。工程师使用RF信号发生器作为测试设备，主要用于测量滤波器，放大器和电气元件的响应。
附加功能：
Agilent E8244A PSG-L系列性能信号发生器可对产品进行精确表征，而无需使用外部放大器来测试大功率设备。Agilent E8244A在20 GHz时提供20 dBm（选件1EA），从而降低了总体设备和测试成本。PSG系列的卓越电平精度（+/- 0.7 dB）减少了测试不确定性并提高了生产量。标准产品在1 kHz偏移下具有-85 dBc / Hz的相位噪声性能，在20 kHz偏移下具有10 GHz载波的相位噪声性能为-110 dBc / Hz。Agilent E8244A的选件UNJ在1 kHz偏移时为-98 dBc / Hz，在10 kHz偏移时为-110 dBc / Hz，并且具有10 GHz载波，从而提供了更高的性能。新的PSG系列Agilent E8244A可确保对设备进行准确的评估，
Additional Features:
The Agilent E8244A PSG-L Series Performance Signal Generator offers accurate characterization of products and eliminates the need of an external amplifier for testing high power devices. The Agilent E8244A provides 20 dBm at 20 GHz (option 1EA) reducing overall equipment and test costs. The superior level accuracy of the PSG series (+/- 0.7 dB) reduces test uncertainties and improves production throughput. Standard products have phase noise performance of -85 dBc/Hz at 1 kHz offset and -110 dBc/Hz at 20 kHz offset and a 10 GHz carrier. The Agilent E8244A provides improved performance with option UNJ of -98 dBc/Hz at 1 kHz offset and -110 dBc/Hz at 10 kHz offset and a 10 GHz carrier. The new PSG series Agilent E8244A guarantees accurate evaluation of devices, errors can be pinpointed early on in the design process thus resulting in a reduced development time.
The E8244A is a 40 GHz RF Generator from Agilent. An RF generator is a tool engineers use to generate sinusoidal outputs while testing electronic equipment. The output will automatically have its frequency varied or swept between frequencies. A “sweep” is one complete cycle of a frequency variation. Engineers use RF signal generators as test equipment, mostly to measure responses of filters, amplifiers, and electrical components.
