FYI - I made an output voltage measurement based on the "Px" settings (on my H4, fw v1.2 from the release .dfu file, o'scope w/ 50ohm input, CW=10MHz, square wave:
Pauto 160mV
P2mA 160mV
P4mA 320mV
P6mA 480mV
P8mA 600mV
The CW frequency was -520Hz off at 300MHz here, so I had to adjust the 26MHz reference frequency a little bit..
