嗨大卫 - 后面板I / Q端口输出I / Q调制信号的模拟同相分量,但它必须来自内部基带发生器。
I / Q端口需要注意的其他事项:该连接器的标称输出阻抗为50Ω,直流耦合。
损坏等级> +3.5 V且DC原点偏移通常为50Ω负载的输出信号电平如下:•0.5 Vpk(典型值)对应于I / Q向量的一个单位长度。
•0.69 Vpk(2.84 dB),π/ 4 DQPSK峰值的典型最大波峰因数,α= 0.5。
•0.71 Vpk(3.08 dB),π/ 4 DQPSK峰值的典型最大波峰因数,α= 0.35。
•通常最大1 Vp-p问候 -

Hi David -
The rear-panel I/Q ports output the analog in-phase component of I/Q modulation signal, but it has to come from the internal baseband generator.
Other things to take note of on the I/Q ports:
The nominal output impedance of this connector is 50Ω, DC-coupled.
The damage levels are > +3.5 V and < −3.5 V.
The DC origin offset is typically < 10 mV.
The output signal levels into a 50Ω load are as follows:
• 0.5 Vpk, typical, corresponds to one unit length of the I/Q vector.
• 0.69 Vpk (2.84 dB), typical, maximum crest factor for peaks for π/4 DQPSK with alpha = 0.5.
• 0.71 Vpk (3.08 dB), typical, maximum crest factor for peaks for π/4 DQPSK with alpha = 0.35.
• Typically 1 Vp-p maximum
