是 - 大多数功率传感器具有非常好的匹配性，因此当您使用具有非常好的回波损耗的传感器测量端口功率时，来自源的大部分功率将被传递到传感器。
另一方面，您的DUT具有较差的回波损耗，反映了更多的功率回到源。
经过校正的S21测量可以解决这种不匹配问题，但如果您想使用S21来计算输出功率，则不能假设平坦的输入事件功率。
为了使用PNA测量输入功率，您还需要至少执行R1接收器功率校准。
但是，为了获得最准确的测量结果，您需要进行匹配校正的功率测量。
如果您碰巧选择083或082，则可以设置标量混频器测量（SMC），偏移为0 Hz，并使用OPwr测量，这将是DUT的匹配校正输出功率。

Yes - Most power sensors have very good match and therefore when you measure the port power with a sensor with a very good return loss, most of the power from the source will be delivered to the sensor. On the other hand your DUT that has a poor return loss, reflects more of the power back into the source. A corrected S21 measurement accounts for this mismatch, but if you want to use the S21 to compute the output power, you can't assume a flat input incident power.
In order to measure the input power with your PNA, you will also need to do at least an R1 Receiver Power cal. However, for the most accurate measurement you will need a match-corrected power measurement. If you happen to have option 083 or 082, you can setup an Scalar Mixer measurement (SMC) with a 0 Hz offset and Simply use the OPwr measurement, which will be the match-corrected output power of your DUT.
