嗨奥斯卡 - 你看到的问题可能是因为IF Gain设置为“Autorange”。
自动量程是早期PXA SW的默认值，但后来在后来的SW中更改为默认为低增益，这解决了问题。
早期的PXA SW Rev A.8.54或更早的SW有这个问题。
SW A.10.04或更新版本解决了这个问题。
但是，用户可以通过进入I / Q分析仪模式手动选择自动量程，按：Meas Setup，More，Advanced，More，IF Gain并手动选择Autorange。
您可以使用此键序列选择低增益设置，以确保您看到的问题消失。

Hi Oscar -
The issue you are seeing is probably due to the fact IF Gain is set to “Autorange”. Auto range was the default with earlier PXA SW, but has since been changed in later SW to default to Low Gain, which solves the problem.
Early PXA SW Rev A.8.54 or earlier SW had this problem. SW A.10.04 or newer fixes the problem. However, it is possible for the user to manually select Autorange by going to I/Q analyzer mode, press: Meas Setup, More, Advanced, More, IF Gain and manually select Autorange. You can use this key sequence to select the Low Gain setting to assure the problem you are seeing goes away.
