| 参数类别 | 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
