Try looking at the full bandwidth of the signal.  The picture you posted
shows -34dBm in a 30kHz bandwidth.  Across the whole bandwidth, you have
more power.

Maybe there's a power/amplitude vs. time measurement, or zerospan with an
appropriate measurement bandwidth on the analyzer?  Or if you just have an
RF power meter?
