对于混音器,所有功率设置均可在SOUR:POW树下使用。
RF和LO功率可以通过SENS:MIX树设置,但是对于更复杂的事情,你需要去SOUR:POW树。
所以,鉴于此,可以直接解耦功率:SOUR:POW:COUPle OFF并设置IF端口的电源,SOUR:POW2 -40可以让衰减器保持自动。
对于n5242a的-40dBm功率电平,自动衰减器将衰减器设置为30dB。
但是,如果要覆盖该设置,可以设置自己的衰减器值:SOUR:POW2:ATT 20设置衰减器后,自动衰减器设置将关闭。
这将确保PNA尊重您所做的设置。

For mixers, all the power settings are available under the SOUR:POW tree. The RF and LO powers can be set through the SENS:MIX tree, but for anything more complicated, you need to go the SOUR:POW tree.
So, given that, it is straightforward to decouple the powers:
SOUR:POW:COUPle OFF
And to set the power on the IF port,
SOUR:POW2 -40
you can leave the attenuator at auto. For a power level of -40dBm on a n5242a, the auto attenuator will set the attenuator to 30dB.
But, if you want to override that setting, you can set your own attenuator value:
SOUR:POW2:ATT 20
Once you set the attenuator, then the auto attenuator setting is turned off. That will make sure that the PNA respects the setting that you made.
