And then there was the engineer (?) who changed the (Signal Generator)-(Switchable Attenuator)-(Amplifier)-(Antenna) setup to:
(Signal Generator)-(Amplifier)-(Switchable Attenuator)-(Antenna) and tried (and fried) all positions of the switchable attenuator when the output was too low.

Yeah, port 0 I believe can push about 12dbm when the osc is set to 8mA (per an
earlier post this year) so as Jim stated, the inputs should be capable of
quite a bit more than that.
However, with that said, it is always wise to use an attenuator(s) on the
ports.
I can remember one of the engineers I worked with figured they could measure
5W with an HP power sensor without using any attenuators. His manager was not
too happy about getting the sensor repaired for $$$
One of those 'life lessons'.....

Given the resistive networks between the connectors and the active devices,

suspect 10mW is very conservative.

Do they really burn out at around 10mW, That is not much. I plan to play

an amplifier putting out more than that. I'll use an attenuator so mine is
safe but accidents happen.
