Hello I try to measure a power of a few tens of mW

I use an analogue power bridge capable of measuring down to 5W scale and I measure a power of 100mW out of the transmitter

Then I use an oscilloscope and I measure a power of 200mW (in Vppk) out of the transmitter

Which one should I trust more for my measurements?
