There is about 0.6 dB AM distortion at 33 dBm full AM keying on two different time scales: one on a few ms and another on a few 10 ms timescale.
Is this expected?

Excluded attenuator, signal source, Booster input RF switch.
This happens on source keying, channel enable/disable and interlock clear.
It's somewhat less bad at lower powers.
