技术指标 |
含义与解读 |
| 增益与平坦度 |
增益 ≥30 dB
增益平坦度 ±1.0 dB/36MHz |
增益衡量信号放大的能力，30dB的增益意味着信号功率被放大了1000倍
。增益平坦度则表示在36MHz的频带内，增益的波动非常小（±1.0 dB），这对于保证宽带信号内所有频率成分被均匀放大至关重要，能有效避免信号失真
。 |
| 线性度与杂散 |
三阶交调 -40 dBc
杂散输出 ≤-60 dBc / ≤-60 dBm
镜像抑制 ≥80 dBc (仅下变频) |
三阶交调是衡量线性度的关键指标，值越低说明设备在大信号下的失真越小，通信质量越高
。杂散抑制和镜像抑制能力出色，能有效减少无关频率成分的干扰，确保信道清洁
。 |
| 本振信号质量 |
相位噪声：
-75 dBc/Hz @100Hz
-80 dBc/Hz @1kHz
本振泄露 ≤-70 dBm |
相位噪声反映了本振信号的频率稳定度，优异的相位噪声性能（特别是在低频偏移处）对提高通信系统的信噪比和降低误码率有极大帮助
。本振泄露控制得很好，意味着本振信号很少泄漏到射频端口干扰其他部件

| 接口与控制 |
衰减控制：0-30dB，步进0.5dB
参考时钟：10MHz，可自动切换
控制接口：网口(RJ45)、串口(DB9)等 |
数字衰减器提供了精确的增益控制能力，步进小，方便系统优化动态范围。外参考时钟及自动切换功能保证了多设备协同工作时的高同步精度
。丰富的控制接口便于集成到各类系统中。 |
| 结构与可靠性 |
工作温度：0℃ ~ +50℃
电源：AC220V, 50Hz, 功耗40W
外形：19英寸1U机箱，约6kg |
宽工作温度范围和环境适应性指标（如增益稳定度）保证了设备在不同环境下的稳定可靠运行。19英寸1U的标准机箱设计便于在机柜中安装和维护，功耗控制得也不错
