Keysight 4395A為實驗室與生產應用，提供了優異的向量網路、頻譜與阻抗選項量測。評估元件與電路通常必須執行的增益、相位、波群延遲、失真、寄生、CN與雜訊等量測，全部可利用一部儀器搞定。
若搭配測試組件，Keysight 4395A可提供如回返損耗、SWR和S參數等反射量測。當作向量網路分析儀使用時，Keysight 4395A的操作頻率範圍在10 Hz到500 MHz之間，解析度為1 mHz，而它的整合合成信號源則可提供-50到 + 15 dBm的輸出功率和0.1 dB的解析度。動態大小與相位準確度為+/-0.05 dB和+/-0.3 deg.，因此能準確地量測增益與波群延遲平坦度，這些對現今的電子系統來說已經愈來愈重要了。
當作頻譜分析儀使用時，Keysight 4395A的操作頻率範圍在10 Hz到500 MHz之間，解析頻寬（RBW）為1 Hz到1 MHz，以1-3-10步進。完全合成的本地振盪器，可讓您執行穩定而準確的頻率分析。直接的A/D轉換（不使用LOG放大器），可提供+/-0.8 dB的位準準確度（在50 MHz，-20 dBm）。雜訊旁波帶在距離載波100 kHz的偏移時，會低於-100 dBc/Hz，而靈敏度在10 MHz時為-145 dBm/Hz。
