Keysight E8257D 是一款全合成信号发生器,输出功率大、相位噪声低,还提供了强大的调制能力。 除非另有说明,仪器在 0 至 55 °C 温度范围内且经过 45 分钟预热后可以实现这些技术指标。 补充特性(标注为典型值、标称值或测量值)提供了仪器在 25 °C 时的额外(非保证)信息,可能对产品应用有所帮助。
具有计量级的频率和电平准确度以及出色的失真和杂散特性,能够满足非常严苛的测试要求
可在宽广的频率范围内进行测量:提供 13、20、31.8、40、50 和 67 GHz 型号(通过扩频器可扩展至 1.1 THz)
借助选件可以生成高达 1 W(+30 dBm)的输出功率,从而能够测试大功率器件并补偿测试系统的功率损耗
获得极低的相位噪声:-91 dBc/Hz(100 Hz 频偏)、-126 dBc/Hz(10 kHz 频偏)(10 GHz),可以满足多普勒雷达、ADC 和接收机阻塞测试的需求
可以向信号添加 AM、FM、PM 和脉冲调制,从而表征器件和电路
