M9403A 和 M9404A 能够为需要长信号路径的应用提供端到端射频/微波链路。它们在 300 kHz 至 26.5 GHz 或 50 GHz 的频率范围内工作，可使用单模光纤技术在达到或超过 1500 米（选件 F26）和 1400 米（选件 F50）的距离上传输信号。由于它们消除了下变频技术本身具有的复杂性和失真，所以类似天线测距或地面站等应用均可受益。
M9404A 光接收机是单插槽 PXIe 模块。提供可选的内部 +27 dB（选件 F26）或 +24 dB（选件 F50）射频放大器，用于改善链路变频损耗。
M9404A 模块经过定制生产和测试，可达到标称值*性能技术指标。它们还经过完整的监管和安全测试。此产品享受与其它是德仪器相同的保修和支持服务。由于它是定制生产的，是德建议您在订购它之前检查其可用性和交付信息。
* 标称值是指在产品应用中有用的代表性能，在 20 °C 至 30 °C 温度范围内有效。标称性能不是保证性能。
